## Adorkable 2 years ago Simplify with Positive Exponents

Basically I'm tying the question

3Root(10x^3)^2/(10x^6)^-1

Please explain how i would do this.

7. UsukiDoll

we're dealing with cube roots, not square roots. which is on of the important steps. STOP! no no anything with a negative exponent goes in the denominator

8. UsukiDoll

9. UsukiDoll

so first of all we need to multiple (10x^3)(10x^3)

Thats part of the questionn

contiue

12. UsukiDoll

ok so... multiplying (10x^3)^2 will give me 10^2x^6 or 100x^6

right

ya i got that

17. UsukiDoll

I can cancel out the x^6''s and 100/10 = 10 since 10 isn't divisible by 3 which is the cube root we are done.

20. UsukiDoll

how can that be?

21. UsukiDoll

oH I see what they did.

22. UsukiDoll

they didn't cancel out the x^6's. funny. it should

23. UsukiDoll

if that's the case 6 is divisible by 3 so we have x^2

24. UsukiDoll

ok now I got it|dw:1366673704430:dw|

25. UsukiDoll

|dw:1366673744692:dw|

26. UsukiDoll

I'm being honest....I truly believe that those x^6's can be canceled out

27. UsukiDoll

because if you just focus on the x^6's for a bit and use elevator rule, I have no x's left

i cant see what u drew in black

29. UsukiDoll

I drew the answer that you have in the key, but I really think that's not correct because again I can cancel out the x^6's
