When dividing variables with exponent, just subtract their exponents as long as they are the same variables (subtract the exponent of the DENOMINATOR TERM from the exponent of the NUMERATOR TERM) also reduce the fractions to lowest terms as for the NUMERICAL COEFFICIENTS.

(25b^6d^6x^3) / (15b^2d^4x^2) = 5/3 b^4d²x

When raising an exponent to a certain number. just MULTIPLY the exponent of the variable with the number being raised.

Since all the terms are raised to the power of 3, we will have:

(5/3 b^4d²x)³ = 125/15 b^12d^6x³ ANSWER
