Answer 2

–(6)–1

= -6 - 1 = -7
none of the choices are correct.

If you meant
-(6)(-1) , then it would be -6

Answer 3

I think you need to use ^ for exponents, to make hings clear. What you typed is very hard to interpret.

(-6)^-1 = 1/(-6) = -1/6
(t^-4)^-9 * t^2 = t^38

Answer 7

[AI-generated answer — Explain Bot]

To simplify the expression –(6)–1, you can follow the order of operations (PEMDAS/BODMAS). Here's how you can solve it step by step:

Step 1: Start by simplifying the expression within the parentheses. The expression in the parentheses is -6.

Step 2: The next operation is to multiply –1 by -6. The product of -1 and -6 is 6.

Therefore, the simplified result of –(6)–1 is 6.

So, the correct answer is 6.
