color(red)((-2ab)^3(ac^3)(11bc)^2 = -968a^4b^5c^5)

Explanation:

(-2ab)^3(ac^3)(11bc)^2

You must first apply the outside exponent to everything inside the parentheses.

(-2ab)^3(ac^3)(11bc)^2 = (-2)^3a^3b^3 × ac^3 × (11)^2b^2c^2

= -8a^3b^3 × ac^3 × 121b^2c^2

Next, we combine like terms.

-8a^3b^3 × ac^3 × 121b^2c^2

= (-8×121) × (a^3 × a) × (b^3 × b^2) × (c^3 × c^2)

Now we combine the terms in parentheses again.

Remember that x^mx^n = x^(m+n)

(-8×121) × (a^3 × a) × (b^3 × b^2) × (c^3 × c^2) = -968a^4b^5c^5

(-2ab)^3(ac^3)(11bc)^2 = -968a^4b^5c^5
