Question

Multiply and simplify q^7* q*q^-9*9^-3

Answer 1

So,

(q^7)(q)(q^{-9})(9^-3)

Multiply compatible exponents.

(q^8)(q^{-9})(9^-3)

(q^{-1})(9^-3)

Simplify.

\frac{9^{-3}}{q}

\frac{1}{729q}

Explanation:

Answer 2

So,


`(q^7)(q)(q^(-9))(9^-3)`

Multiply compatible exponents.

`(q^8)(q^(-9))(9^-3)`

`(q^(-1))(9^-3)`

Simplify.

`(9^(-3))/(q)`

`(1)/(729q)`
