Hello folks, I was wondering if maybe I could find a little help on 3 homework questions I am stuck on.
First one is 9x to the 4th power y to the -3rd power z to the 8th power divided by 12x to the -4th power and in parentheses y to the 7th power plus z to the 4th power with 0 power outside the parentheses on the right. The whole problem is surrounded by brackets like this [] to the -3rd power.
the second problem I can just type out is 2ab-{7ab-[2a-2ab-8(2b-ab)]}+ab
I just multiplied what was in the parentheses and pretended that the other brackets were not there since I think those were just thrown in to confuse me, and then combined like terms to get an answer of 2ab-2a-16b. Is that correct?
the 3rd problem I am stuck on is finding the area of a triangle with a base 2 inches and height of 4 inches?
Thanks in advance,
