Just wanted to check over these..
"What is (–7)^5 in expanded form?
–7 • –7 • –7 • –7 • –7
–7 • 5
(–7) • 7 • (–7) • 7 • –7
5 • 5 • 5 • 5 • 5 • 5 • 5"
The answer is "–7 • –7 • –7 • –7 • –7", right?
Also:
"Which expression is equivalent to 4 • 4 • 4 • 4 • 4 • 4 • 4 • 4?
4 • 8
8^4
8 • 8
4^8"
4^8, right?

for the 1st, if those are your only choices, you are correct, most would prefer
(7)(7)(7)(7)(7)
