move the decimal point to the left 9 spaces.\n.000000004.

10^3 = 1000\n\nSo 2.8 * 10^3 = 2.8 * 1000 = 2800\n\nOr you can just look at the power of 3 and move the decimal place to the right by 3 places.\n\nSimilarly,\n\n4.7 * 10^-2 = 0.047\nBecause the power of -2 would imply moving the decimal place by 2 places to the left. Or you could divide 4.7 by 100.\n\nThis form of writing very big or small numbers is called standard form.

Scientific Notation is just a way of expressing VERY small numbers or VERY large numbers so we don't have to perform or write equations and figures like 187,000,000,000,000,000,000,000,000 x 4,500.\nInstead, it's much simpler to write:\n(1.87 x 10 to the 26th power)(4.5 x 10 to the third power)

Here's the best I can do. The answer I got is:\n\n24x^4 - 10x^3 + 690x^2 + 3190x = 1217

Or is it this:\n300+20+4\n400+60+7\n100+10+1\n800+90\n60+8\n1000+600+50+4

Decimal is the normal way to write numbers: .00002\nScientific notation is 2x10^-5\nTo do this just move the decimal over to the right (-) an count the number of 0's you pass and put 10 to that power.  If you move the decimal to the left then the power is positive.\n\nWhy do scientist do this?  In our solar system there are some very big numbers like 360,000,000,000,000.  It is easier to just write 3.6x10^14.  There are also numbers that are very small such as in atoms.  Hope this helps.

Expanded form would be\n\n30000 + 2000 + 500 + 1\n\nelse writen as\n\n3x10^4 + 2x10^3 + 5x102 + 1

4.3 x 10^5 = 430,000\n\n4.3 x 10^-5 = .000043\n\nYou just move the decimal either left or right, based off of the exponent.  If it's 5, you move it the right 5 spaces.  If it's -5, you move it to the left 5 spaces.  Fill in empty spaces with zeros.\n\nIf you have a specific question, email me, otherwise, that's really all there is to it.

10 to the 4th power is 4 zeroes after 1 that is 10000.Therefore 3.6X10 the fourth power is 3.6 X 10000.And you know,how easy it is to multiply a number by 10,100 ,1000 or 10000 .just shift the decimal by number of places to the right side as many zero/zeroes are there in the multipler[and if there are not sufficient digits in the multiplicand add required number ot zero/zeroesto the multiplicand  to enable you to shift the decimal.So 3.6x 10000=36000.Now,the second problem d=9.4X10 to the fourth power=9.4 X 10000=94000 km

1)  √10 · ³√100\n= 10^(1/2) · 10^(2/3)\n= 10^(7/6)\n\n2)  (6x)^(1/2) · (36x²)^(1/4)\n= (6x)^(1/2) · (6x)²^(1/4)\n= (6x)^(1/2) · (6x)^(2/4)\n= 6x\n\n...and so on.  Change the radicands to rational exponents with common bases, and follow the rules from there.  Good luck!

Order of operations: Parentheses Exponent Multiplication Division Addition Subtraction.\n\n2 - 2[4-9] ÷ (-5)\n2 - 2[-5] ÷ (-5)\n2 - [-10] ÷ (-5)  ~~ same as 2 + 10 ÷ (-5)\n2 + [-2]  ~~ same as 2 -2\n= 0\n\nI'd double check that if I were you; it's a bit early for me. :*)

Use PEMDAS !!!\n\nIt stands for the order of operations:\n\nP  = Parenthesis\nE  = Exponents\nMD = Multiplication and Division\nAS = Add and Subtract.

it doesnt it is a symbol meaning 10^-9

It means power of 10 (it's a shorthand for scientific notation).\n\nSo your equation is:\n\n(1*10^-230)*e^(0.2682*x)\n\nWhere lower case e is the mathematical constant e (2.718...).

exponents. for example 2^2 would be 2 to the power of 2 which would be 4. 2^3 would be 8. I hope this helped.
