## thefluffmuncher one year ago Need help finding the simplest radical form of 70

1. misty1212

do you know how to factor 70?

2. thefluffmuncher

no

3. misty1212

i don't believe you what number goes in to 70 evenly?

4. thefluffmuncher

10?

5. misty1212

ok so $70=10\times 7$ is a start now can you factor $$10$$?

6. thefluffmuncher

5*2?

7. misty1212

right therefore $70=2\times 5\times 7$ notice it has 3 factors, but none are squared

8. thefluffmuncher

ok

9. misty1212

so $\sqrt{70}$ cannot be written any differently, it is already in simplest radical form

10. thefluffmuncher

oh

11. thefluffmuncher

thanks
