Question

A²-b when a = 8 and b = 7

Answer 1

57

Explanation:

a = 8

b = 7

a² - b

= 8² - 7

= (8*8) - 7

= 64 - 7

= 57

Answer 2

Explanation:

You just plug in 8 as a, and 7 as b. This gives you the following equation:
`(8)^2-7` which becomes
`64-7` by squaring the 8, Then subtract 7 and you get
`57`
