No one helped me please please please help please
Softa [21]

Answer: 1/36

Step-by-step explanation:

Calm down, I'm here to help! You might want to watch some videos on how to solve negative powers, but it's simpler than you think.

An exponent expression is formatted as a^b.

If "b", the exponent, is negative, then you can solve expression like this:

1/a^-b

By writing -b, I mean the opposite of b. For example, the opposite of -2 is 2.

Let's use that rule to solve this problem.

1/6^-(-2)

1/6^2

1/6*6

1/36

There you go! It's not too scary now, is it? Let me know if you'd like me to link some resources!
