Hello stanger!

2. anonymous

$(3\div \sqrt{75})-5$

3. anonymous

plz help :D

4. Defiance

First find 75 squared

5. Jhannybean

$\frac{3}{\sqrt{75}} -5$

6. anonymous

I MESSED UP 75 should be 11!!!

7. Defiance

square root*

8. anonymous

9. Defiance

Okay.

10. Jhannybean

$\frac{3}{\sqrt{11}}-5$ is this your problem?

11. anonymous

yes

12. Jhannybean

$\frac{3}{\sqrt{11}} - \frac{5}{1}$ what is the LCD between $$\sqrt{11}$$ and 5?

13. Jhannybean

sorry,$$\sqrt{11}$$ and $$1$$ **

14. anonymous

1? :/

15. Jhannybean

Not quite, it'd be the multiplication of both of these, $$\sqrt{11} \cdot 1 = \sqrt{11}$$

16. anonymous

and then what?

17. Jhannybean

Now we need a common denominator of $$\sqrt{11}$$ for both fractions so we need to multiply the numerator and denominator of $$\dfrac{5}{1}$$ by $$\sqrt{11}$$

18. Jhannybean

Then we get $\frac{3}{\sqrt{11}} - \frac{5\sqrt{11}}{\sqrt{11}} = \frac{3-5\sqrt{11}}{\sqrt{11}}$

19. Jhannybean

Not exactly sure what you were looking for though, hmm..
