Hello @vegangirl063 ! Welcome to Openstudy!

Is it like this
\(\Large a+1=\sqrt{b}+1\)

or like this?
\(\Large a+1=\sqrt{b+1}\)

Answer 3

Thank you! =)) and its the second one

Answer 4

Okay. So we're solving for b. That means we need to get b alone on one side of the = sign. Notice how b is under a sqrt? Do you know how to get it out?
Hint: What's the opposite of taking the sqrt of something?

Answer 5

cancel the square root by multiplying by the 2nd power on both sides.
