but what if you had, now this is an example ^3/-8/27 square root?

I think you mean find the cube root of -8/27:\n\nCube root of a negative is negative.\nCube root of 8 is 2\nCube root of 27 is 3\n\nSo the answer is -2/3

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.

3^3 + 3 + 3/3 = 27+3+1 = 31

27 = 3^3\n\n27^(2/3) = (3^3)^(2/3)\n= 3^(3*2/3) [ because (a^b)^c = a^(b*c) ]\n= 3^(2)\n= 9

It will be 1/(x^2)\n\nFor example\n\n(1/2)^2 = (1^2)/(2^2) = 1/ 4\n(1/3)^2 = (1^2)/(3^2) = 1/ 9\n(1/4)^2 = (1^2)/(4^2) = 1/16\n\nSo the result actually gets smaller even though you are squaring it

Nah, sorry, but something in your thinking is incorrect.  You seem to be saying that if you add the square root of 3 four times, you want to get 9.  That's not right.  If you take sqrt(3)^4, you WILL get 9.   Taking the fourth root of a number is not like dividing a pie into four pieces.

Just type it into google search   27^3   they have a calculator built in

When we square a number we multiply it by itself\n\nThe square root of a number is the number that when multiplied by itself makes that number.\n\nFor example:\n\nThe square root of 9 is 3 (3 * 3 = 9)\n\nThere are different ways of finding the square rot of a number (by hand - using a calculator is just too easy lol) and the source below shows you some of them.

take 3 as a common factor\n=3(x^2-4x-8)\n=3((x-2)^2-12) putting in form of square\n\nthis has got a minimum

I think you are saying this:\n\nx < sqrt(5)

are u sure its not supposed to be the other way around. Cuz that would make a little more sense.\n\nBut if not, then it would probably be:\n1 + ((4s squared - 11) / (s to the 4 - 3s squared -11))\n1 the quotient. the rest the remainder.

in standard form yes, but thats not the whole answer, the answer would be x to the 2 power and -1

√3 (√3+2) is of the form a(b+c)\na(b+c) = (ab+ac)\nso we simplify to \n√3√3+√3*2\n√a√a = √a*a = √a² = a\nso it's 3+2√3.\nThe rules for roots are exactly the same as the rules for exponents, since a (square) root is merely a exponent of (1/2).  A cube root is an exponent of (1/3).\nⁿ√a root is the same as a^(1/n).

3/x  + 1    the way you put it..

Because I like to waste time I'll answer this. If somebody tells you to simplify the square root of 8 you'd need to take two numbers out and on of them has to be a perfect square or a number that has an exact square root with no remaining numbers. So. Since 8 is not a perfect square you have to break it up. Take 4 and 2 out of it because 4 and 2 multiply to get 8. So take the perfect square of 4 and bring it outside the house (to the left) and leave the 2 (already a perfect square in the house). So. You would get 2 (radical sign) 2. Another example would be 56. You'd get 2 (radical sign) 14 because if you square 2, to get 4 and multiply it by 14 you get 56. You can't do 64 because it already has a perfect square: 8, because 8 times 8 is 64 and you don't need to break it down. If you still dont get it just talk to a teacher.
