Answer:
Step-by-step explanation:
(x + 3)^1/2 = 5
⇔
√(x + 3) = 5
⇔
(x + 3) = 5²
⇔
x + 3 = 25
⇔
x = 25 - 3
⇔
x = 22
Answer: x = 22
Step-by-step explanation: If you raise each side of the equation to the power of 2, you get (5)^2 = ((x + 3)^1/2)^2
Then the 1/2 and the 2 cancel out and you are left with 25 = x + 3
subtract 3 from both sides. 25 - 3 = x + 3 - 3
Simplify 22 = x
