I think this is what you want? When multiplying with exponents, you either add or multiply the exponents.
When you multiply the exponent:
(x²)³ = 
= 9
When you add the exponents:
(x²)(x³) = 
(x²)(x²) = 

Answer: I assume you mean surface area of a sphere.
The formula is 4πr²
If radius=3, then:
4 times
times 3²
4 times
times 9
= 113.142857
Rounded to 1 decimal place = 113.1
<u>NOTE: In place of π you can also use 3.14.</u>
It wont open it up, so no one can really help
Let's do this step by step:
20-3(m-1)=-4
20-3m+3=-4
23-3m=-4
-3m=-27
m=9
To check if this answer is correct, simply substitute m with 9 and you will get 9=9
