Question

What is the value of x in the following equation: 5 = (x + 3)^1/2

Answer 1

Answer:

x = 22

Step-by-step explanation:

(x + 3)^1/2 = 5

⇔

√(x + 3) = 5

⇔

(x + 3) = 5²

⇔

x + 3 = 25

⇔

x = 25 - 3

⇔

x = 22

Answer 2

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
