Answer:

61

Explanation:

If you use

Parentheses

Exponents

Multiplication

Division

Addition

Subtraction

or PEMDAS, you will eventually get 61

Substituting x

(4*3^2)+5^2= (Use Exponents first)

(4*9)+5^2= (Use Parentheses now)

(36)+5^2= (You can get rid of the Parentheses)

36+5^2= (Use Exponents again)

36+25= (Now Addition)

61

Answer:

73

Explanation:

If you are to use Order of Operations, which most people know as PEMDAS, you come up with the following answer.

I will show my work below. Refer to it if you need to.

4x^2+5^2

16x+25

x=3, so 48 + 25

73
