Question

$\sqrt{a} + 3 = 5$

Explanation:

Step1: Isolate the square root term

Subtract 3 from both sides of the equation $\sqrt{a} + 3 = 5$.
We get $\sqrt{a}=5 - 3$.
Simplifying the right side, we have $\sqrt{a}=2$.

Step2: Eliminate the square root

Square both sides of the equation $\sqrt{a}=2$ to solve for $a$.
Using the property $(\sqrt{x})^2=x$ (for $x\geq0$), we get $(\sqrt{a})^2 = 2^2$.
So, $a = 4$.

Answer:

$a = 4$
