Question

What is the value of the expression?The numbers are -7 and 7

Answer 1

Given the expression:

`5\cdot(-7)^2/7`

You can rewrite it in this form:

`=(5\cdot(-7)^2)/(7)`

You need to follow these steps in order to find the value of the expression:

1. Solve the Power. Remember that:

`(-7)^2=(-7)(-7)=49`

Then:

`=(5\cdot49)/(7)`

2. Since there is a Multiplication in the numerator, you can try to simplify. Notice that:

`(49)/(7)=7`

Then:

`=5\cdot7`

3. Finally, you have to solve the Multiplication:

`=35`

Therefore, the answer is:

`=35`
