Answer:
b=40
c=12
Step-by-step explanation:
b) 3+7(8-6)2
10(2)2
20^2 =40
C) 4+(−3) 2 −2÷( 6/3)
4+9− 2/6/3
13-2/6/3
13-2x3/6
13-6/6
13-1
c=12

Answer:
4² = 16
Step-by-step explanation:
The applicable rule of exponents is ...
1/a^-b = a^b
So, ...
_____
<em>Additional comment</em>
If you were to evaluate this using the Order of Operations, you would evaluate the exponent first:
1/4^-2 = 1/(1/16)
Then, you would do the division.
1/(1/16) = 16
__
We sometimes find it convenient to manipulate exponential terms to the form with the smallest positive exponents before we begin the evaluation.
