Answer 1

Answer:

$\frac{\sqrt{15} }{5}$ and 16 is a solution to the original equation.

Step-by-step explanation:

To rationalize, you take

$\frac{3 }\sqrt{15}$ times $\frac{\sqrt{15} }{\sqrt{15} }$

This will come out to be $\frac{3\sqrt{15} }{15}$ It then simplifies to $\frac{\sqrt{15} }{5}$.

To cancel out a square root, square both sides. You'll find w = 16
