Question

How do you solve `sqrt(x+1) = 8`?

Answer 1

x=63

Explanation:

`sqrt(x+1)=8`
Now you have to square both sides to cencle out root.

`(sqrt(x+1))^2=8^2`
`x+1=64`
`x=64-1`
`x=63`

In order to verify: `sqrt(63+1)=8`
`sqrt64=8`
`+-8=8`
In the verification `+-` is just because of the rule any number squared gives a positive value. Accordingly `(-8)^2=64` as well as `8^2=64`.

The previous answer was not correct.
