When multiplying two values of the same base raised to different exponents, all you need to do is add the exponents. Similarly, when dividing them, you can simply subtract the exponents.
In the case of roots, the exponents are actually fractions, so you get:
x1/2 ÷ x1/3
= x(1/2 - 1/3)
= x(3/6 - 2/6)
= x1/6

root 27 = root 9 x root 3 = 3 root 3. Dividing this by root 3 gives 3!
64 x 64 x 64 = 262,144√ 262,144 = 512Another way of arriving at this is to take the square root of 64, and cube it - 8 x 8 x 8 also = 512
x3/x1/2 = x5/2.

square root is 8 (8 x 8 = 64)cube root is 4 (4 x 4 x 4 = 64)
x=y
replace square root o x with t.
the square root of x*x is x if there is a 3 then a square root it is acutally cube root. the cube root of x*x*x is x if there is a 4 then a check symbol then that is fourth root. the fourth root of x*x*x*x is x. the square root of 16 is 4(4*4=16). the fourth root of 16 is 2(2*2*2*2=16).
The fraction must be rationalized. Since it is the square root of x in the denominator, you are going to multiply the numerator and denominator by the square root of x. For simplicity of the problem, root will take the place of the symbol for square root: root(3y)/root(x) root(3y)*root(x)/root(x)*root(x) root(3xy)/x The simplified answer is going to be the square root of 3xy divided by x. Hope that helped.

x ∈ C, x ≠ 0
The square root of a perfect square and the cube root of a perfect cube is always an integer. A perfect square is a number multiplied by itself. A perfect cube is a number multiplied by itself twice. Example: 3 x 3 is 9, the square of 3 3 x 3 x 3 is 27, the cube of 3
Cube root it. the square of a cubed number can be divided into 3 equal squares (Ae3)e2 = Ae(3x2) or Ae6 this is also equal to (Ae2)e3 as long as a number can be expresses as a root number with an exponent equal to 6 the cube root of that number is a square of the root Example: 64 can be divided into 8 x 8 or 4 x 4 x 4 64 is the square of 8 and the cube of 4 4 is the square of 2, 8 is the cube of 2 per the above formula: (2e3)e2 = 2e6 = (2e2)e3 = 8e2 and 4e3 more simply: 2 x 2 x 2 x 2 x 2 x 2 = 64 8 x 8 = 64 (64 is a square) 4 x 4 x 4 = 64 (64 is also a cube) 2 x 2 = 4 (4 is a square)
It means it is a different kind of root, such as a cubic root, which has a three above the square root symbol ('radical sign'). If y is the square root of x, it means that y2 = x. So the square root of 4 is 2, and 22 is 4. If y is the cube root of x, it means that y3 = x. So the cube root of 8 is 2, and 23 = 8.
