Question

I'm doing a practice test to prepare for my algebra 2 math exam and I have no idea what the answer would be here.​

Answer 1

Answer:

It is the first one

Step-by-step explanation:

2 square root 15 x over 5x

you factor each number and then separate them

Examples to help solve the questions

• $\sqrt[n]{ab}$ =$\sqrt[n]{a}$$\sqrt[n]{b}$

• $\sqrt[n]{a}$= a^1/n
• $\frac{x^a}{x^b}$=x^a-b
• a^1/n=$\sqrt[n]{a}$

also $\sqrt{15x}$ = 15^1/2

I hope this helped :)
