    we're dealing with cube roots, not square roots. which is on of the important steps. STOP! no no anything with a negative exponent goes in the denominator

    ok so... multiplying (10x^3)^2 will give me 10^2x^6 or 100x^6

    I can cancel out the x^6''s and 100/10 = 10 since 10 isn't divisible by 3 which is the cube root we are done.

    if that's the case 6 is divisible by 3 so we have x^2

    I'm being honest....I truly believe that those x^6's can be canceled out

    because if you just focus on the x^6's for a bit and use elevator rule, I have no x's left

    I drew the answer that you have in the key, but I really think that's not correct because again I can cancel out the x^6's
