The way that you would do this is by taking
out of the binomial, or as I like to think about it, 'un-distributing'. :p
out of
, you end up with
.
When you take
out of
, you get
.
Put it together, and the solution is
-
.
Hope I helped!!
The rectangle has an area of 18x8 = 144 sq in. The circle has an area of (pi)r^2 or (pi)3^2 =28.27sq in. Subtract 144 - 28.27 = 115.73
Answer: In my honest opinion, I think they’re both beautiful. Everybody has at least one unique thing that the other person doesn’t.
You can put the numbers where the variables are and do the arithmetic, or you can simplify the expression first. In the latter case, you have
(3a^(-2-(-1))b^(6-5)/2)^2 = (3a^(-1)b^1/2^2 = (3b/(2a))^2
= (3(-2)/(2(3)))^2 = (-1)^2 = 1
The value of the expression is 1.
