Step-by-step explanation:
Remark
This is a bit ambiguous. I'm going to take it to mean
√(4t + 5) = 3
Solution
√(4t + 5) = 3 Square both sides.
(√(4t + 5) )^2 = 3 ^2 If you square something and a √ is involved, sometimes squaring something will get rid of the√ sign. That's what happens here.
4t + 5 = 9 Subtract 5 from both sides.
4t + 5 - 5 = 9-5 Combine
4t = 4 Divide by 4
4t/4 = 4/4
t = 1
