Question

Can someone help me solve this equation?

Answer 1

Yes. Why don't you use the property that \[\sqrt{u}\sqrt{u} = u\]to start? In other words, square both sides.

Answer 2

I figured it out. Is the answer 34?

Answer 3

Let's check:
\[\sqrt{2(34)-4} =8\]\[\sqrt{68-4}=8\]\[\sqrt{64}=8\]\[8=8\checkmark\]Good work!

Answer 4

Thanks so much for your help!

Answer 5
