2^34 what does this mean?

i means you multiply 2*2*2... all the way to 34 times...

dont the value of x have to be the same? to the person above me..\n\ni thought that x^2 means x to the power of 2 (x squared)\nooo wait i dont know im confusing myself. im only 13 and not that smart but these are my answers now.\n\n\nfirst i got x= negetive eight.\nthen i got x= 2 and -8\n\n\nand gary, wow thats befuddling.\nyour a nerd.\n\nwhat are you kidding me?? thats so not seventh grade math! thats algebra, and im only in pre algrebra.

It means "to the power of". Used for indices \n\neg. 4^5 is 4 to the power of 5

Binary digits stand for powers of 2.  For example, 2^0 is 1, and 1 in binary is 1.  2 is equal to 2^1, so 2 is 10 in binary.  3 is 2^1 + 2^0, so it's 11 in binary.  \n\nSo the joke is really saying there are 2 types of people.  Now you fall into the former.  :-)\n\n*** There are two types of people, those who know binary and those who don't, now you fall into the former category of those who know.

The domain is [0, pi/4), (pi/4, 3pi/4), (3pi/4, 2pi]\n\nThe range is [-1, -infinity), [1, infinity).\n\nJust in case, [ means "number next to it included" and ( means "number next to it not included." so [a, b) means from a (a included) to b (b not included.)

I'm not sure if the x is supposed to be the multiplication symbol or a variable.\n\nIf you mean 2*(4*2) or 2(4*2), the result is: 16\n\nIf it is the letter "x", the answer is:\n2x(4*2) = 2x(8) = 16x

There's a difference.  It refers to (sin x)^2.  Plug in a few numbers and you can easily tell the difference.

This is an ambigous way to write the function, there are a couple of answers:\n\nIf it means:\n(5)(2x)-3x+1\nIt equals -13\n\nIf it means:\n(5)(2)-3x+1\nIt equals 17\n\nIf it means:\n5x^2-3x+1\nIt equals 27

so it's asking for 5*2*-3, and then subtract 4\nso -30 - 4 is -34

what it means is this 4 plus negative .01 and with the other it's 5 plus negative .04 its simple. if you know what it means and if you took notes look at them. it may help a little

Its 2^0+2^1+2^2+2^3+....+2^63.\nThe sum of powers of 2 till 64. \n\nthe speed of a 64bit processor?

x² is "x to the power 2", or "x squared"\n\nIt means "x times x"\n\nOften times you'll see this written as x^2 which also means x squared, or x to the power 2.  The ^ notation helps when you can't easily type a superscript number.\n\nFor example x^3 means "x to the power 3" or "x cubed" and it equals x * x * x.  \n\nAfter 3, you'll just hear "x to the power 4", "x to the power 5" etc.  Or sometimes people will say "x to the 4th power", "x to the 5th power", etc. There are no equivalent terms to "x squared" or "x cubed" for powers 4 and beyond.

Those other folks are underestimating it hugely.  Written as 9^(9^9), it's equal to 9 to the power 387420489 and is roughly equal to 4.281455x10^369,690,399.  That's a 4 followed by almost 370 million more digits.

Remember how powers are defined. 2^3 = 2*2*2. So, a nice feature of exponents is that multiplying numbers adds the exponents = for instance, 2^3*2^4 = (2*2*2)*(2*2*2*2) = 2^(3 + 4) = 2^7\n\nNow, lets say you have the problem 2^7*2^x = 2^4. How would you solve this? By the nice exponent property above, this is the same as 7 + x = 4, so x = -3. But expanding these out, 2^7 = 128, 2^4 = 16, so 2^-3 should be 1/8.\n\nThis is also why anything (except 0) to the 0th power is 1:\n\na^x*a^0 = a^(x + 0) = a^x, so a^0 = 1

WTF? - Your question makes no sense.  I suppose you mean TWO consecutive numbers multiplied together...\n\nBut in that case the answer is impossible:\n\nIf the two consecutive numbers are A and A+1\n\nA x A+1 will be greater than A^2 and less than (A+1)^2  i.e. it will always be between two squares.\n\n:-/\n\n.

As the hint says, every number is some power of two multiplied by an odd number, or 2^j * s, where s is odd.\nNow, lets say you have written every number in the set T like that. What possible values for s have you come up with? They all have to be <= 2n-1, since the whole number is <= 2n. That means there are precisely n possibilities: 1, 3, .., 2n-1.\nHowever, you have chosen n+1 numbers. So two of those numbers must have the same 's' part.\nBut then if the numbers were 2^a * s and 2^b * s, one of those numbers is a multiple of the other - assuming a>b, (2^a * s)/(2^b * s) = 2^(a-b) (and similarly for a<=b).

first of all this 2^x+2-2^x+2-2^x+24 is NOT an equation, since it DOES NOT have an equal sign....\nbut:\n2^x+2-2^x+2-2^x+24 = 2+2-2^x+24 = 28 - 2^x\n`
