Re: cube root of x^6

Thanks.

So the nth root of x = x^1/n ?

Re: cube root of x^6

Hi,

In (xi), a = b because the powers are same and when you remove the powers; example by rooting both sides, you'll get the equation a=b. a^2 and b^2 are only equal if a and b are positive integers. Eg:  2^2 = x^2; then x = 2 or -2. 3^2 = y^2; y = 3 or -3............ You can check this yourselves.
