Question

Write the expression (−2)·(−2)·7·7·7·7·7 using exponents.

Answer 1

Answer:
`(-2)^(2)*7^(5)`

Explanation:

You have to group all of the same one's together and however many there is, you add that number as the exponent.

There were 2 "(-2)" so that became
`(-2)^(2)`, and there were 5 "7" so that became
`7^(5)`. You keep the symbol and put it together which became
`(-2)^(2)*7^(5)`
