Question

Ok, I don't have a question, so I am just doing this for fun. This is for 7th-8th graders, I am higher than those grades

If x=3, what is the value of :(4x^2)+5^2?

Answer 1

Answer:

73

Step-by-step 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

Answer 2

Answer:

61

Step-by-step 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
