(18(x^(2)y)^(3))/(9x^(6)) ⋅

Question

Please help me pleeaassseee.!

Answer 1

I read this as (18(x²y)³)/(9x⁶).

Let's deal with the numerical constants first:

(2(x²y)³)/(x⁶).

Let's expand (x²y)³. All the exponents inside parentheses are to be multiplied by 3:

x⁶y³. But we also have x⁶ in the denominator so it cancels x⁶ in the numerator leaving us with the solution:

2y³.
