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.

The correct answer is D. I've had that question before
<em>Answer:264 students</em>
Step-by-step explanation:You have to add to get you answer.I'll show you how I got 264:
12+12=24
24+36=60
60+36=96
96+21=117
117+21=138
138+63=201
201+63=264
Your answer is: 264 students
Answer:
Step-by-step explanation:
x² - y² = (x + y)(x-y)
c² - (5b - 3a)² = (c + [5b -3a]) ( c - [5b - 3s] )
= (c + 5b - 3a) (c - 5b + 3s)
