1. completeidiot

$\sqrt{\frac{17}{17}-\frac{9}{17}}$ this?

2. carlenstar281

no sorry thats not the equation its

3. completeidiot

unable to view attachment

4. carlenstar281

crap I can draw it either its not letting me

5. completeidiot

$17\sqrt{17}-9 12 \sqrt{17}$ ??? please be a bit more specific

6. carlenstar281

ya thats the equation and I have to simplify it

7. completeidiot

wait 912? are you sure thats right? its kind of a large number

8. carlenstar281

no -9 and then square root sign between

9. carlenstar281

by the way thank you for trying to help me I appreciate it

10. completeidiot

$17\sqrt{17}-9\sqrt{12}\sqrt{17}$ this?

11. completeidiot

sigh soooo$17\sqrt[2]{17}-9\sqrt[2]{17}$

12. carlenstar281

no power of 2 but yes thats right without the 2's though

13. completeidiot

$17 \sqrt{17}-9\sqrt{17}$

14. completeidiot

SAME THING

15. completeidiot

anyways, are you familiar with factoring or distributive property of multiplication or adding like terms?

16. carlenstar281

sorta

17. completeidiot

ok, look at both terms, notice that they're both multiplied by sqrt(17) this means you can factor it out $17\sqrt{17}-9\sqrt{17}= \sqrt{17} (17-9)$

18. carlenstar281

oh okay I get that

19. completeidiot

ok well then the only thing left is 17-9

20. carlenstar281

right so the answer is 8

21. completeidiot

17-9 is 8 but 8 alone isnt the final answer

22. carlenstar281

8/0?

23. carlenstar281

oops i mean 8/17

24. completeidiot

assuming that slash means sqrt sign then yes normally "/" means divided by

25. carlenstar281

haha ya it does thank you for your help :)
