Some math problems so yep help pls

Step-by-step explanation:

Take this one thing at a time...baby steps to help us keep our sanity. Math does tend to drive a person around the bend...

The first term is the tricky one. If the exponent is negative, it can be rewritten as a positive by putting whatever the exponent is on under a 1. For example:

So we'll use that to make this simpler.

 Squaring that negative makes it a positive, so we can rewrite as

which simplifies to

 What we have there is a fraction over a fraction; namely:

and the rule for that is to bring the bottom fraction up, flip it and multiply:

× which is 4.

Now for the second part. All we are doing here is squaring that fraction. Remember that squaring a negative makes it a positive, so

. Now we'll put these together to get the sum

and with a common denominator of 4, this becomes

and that equals

, the seond choice down.

answer: the two figures are congruent.

step-by-step explanation: they're congruent because figure efgh is reflected across the x and y axis but it was also rotated.

hope it !
