What is (4ab^0c^9)^3 ?

fomenos

Answer:

64a³c²⁷

Step-by-step explanation:

The expression inside parentheses can be simplified by noting that b^0 = 1. Then you have ...

(4ac^9)^3

The rules of exponents say the exponent outside applies to each of the inside factors. For c^9, the exponents multiply.

Here are the applicable rules:

(ab)^c = (a^c)(b^c)

(a^b)^c = a^(b·c)

(4ac^9)^3 = 4^3·a^3·c^(9·3) = 64a^3c^27
