Question

EXPONENTS HELP: Choose the correct expanded form for (-3b)5

a. (-3b)(-3b) (-3b)(-3b)(-3b)
b. (5)(-3b)
b. (-3)5b^5

Answer 1

a

just as
`x^(5)` = x × x × x × x × x

that is x multiplied by itself 5 times, then

`(-3b)^(5)` = (- 3b)(- 3b)(- 3b)(- 3b)(- 3b)

that is (- 3b) multiplied by itself 5 times
