what expression

Answer 2

\[\sqrt[3]{128a ^{13}?}b ^{6}\]

Answer 3

the square root covers the whole expression

Answer 4

cant help you there sorry

Answer 5

Take each factor under the square root, and if the exponent is not a multiple of 3, separate it into two factors. One of the two factors has to have an exponent that is the largest multiple of 3 in the exponent.

\(b^6\) already has an exponent that is a multiple of three, so don't do anything to it.

For example, \(128 = 2^7 = 2^6 \times 2\)

Can you do the same to a^13?
