Write using exponents. (–4)(–4) a. -4^2 b. (2)^-4 c. (-4)^2 d. 2^-4

Remark

Using brackets, as the question has, each of the minus signs is part of the 4. That means you have 2 minus signs in total. They are multiplied together.

Two minus sign's = a plus.

Argument

D is wrong.

The power is not made minus. That would be an entirely different problem. The power and the base have been interchanged. So D has 2 mistakes.

B is also wrong for the same reason.

The power and base have been interchanged. The fact that there are or are not brackets does not make any difference.

A is wrong.

There is only one minus sign given. That cannot happen when there were two to start with.

Answer C.

The two minus signs are preserved. The 2 as a power affects both minus signs.

affects both of them.

correct answer is infinitely many solutions

step-by-step explanation:

2(2x + 3) = -4 + 2(2x + 5)

solving the above equation:

4x + 6 = -4 +4x +10

combining like terms

4x -4x = -4+10-6

0=0

since both sides are 0=0, we end up into true statement it means it has infinite many solutions.

so correct answer is infinitely many solutions

hope this is what you were asking for!
