Question

Which is the correct solution to the expression 3 + 5 ^ 2? Use the scientific calculator given in this course

Answer 1

28

Explanation:

Using PEMDAS (or something similar) start off with the exponent.

5^2 would equal 25 since it is multiplying 5 by itself.

Then, you would add 3 to 25 making the answer 28.

Answer 2

For this case we must find the value of the following expression:

`3 + 5 ^ 2 =`

We have that, replacing in a calculator:

`5 ^ 2 = 5 * 5 = 25`

Rewriting the expression we have:

`3 + 25 =`

Equal signs are added and the same sign is placed:

`3 + 25 = 28`

Answer:

`3 + 5 ^ 2 = 28`
