Question

Simplify 5(1+3)^2. Best answer appreciated.

Answer 1

80 or 5(4)^2 
you first do parenthesis and then the square root 
so you would have 5(4)^2
Then, you would do the square root and it would come out to
5(16)
You can simply multiply from there, 80.

Answer 2

The answer you are looking for is 80.

This can be found by using PEMDAS. First you'd solve the parenthesis. 1 + 3 = 4.
Next you'd solve the exponents. 4 ^ 2 (4 * 4) = 16.
Finally you'd multiply 16 by 5 to get an answer of 80.

I hope this helps!
