2. King

$\sqrt{a ^{5b ^{10}}}$

3. King

??is this it?

4. mathslover

see : $\huge{\sqrt{ab}=\sqrt{a}*\sqrt{b}}$

5. King

oh!sry!

6. mathslover

DO the same thing ehre : $\huge{\sqrt{a^5 b^{10}}}$ $\huge{\sqrt{a^5}*\sqrt{a^{10}}}$

7. mathslover

u can solve it further .. tell me if u r having problem

8. King

umm.. @mathslover shouldnt it be sqrtb^10?

9. mathslover

oops sorry .

10. mathslover

$\huge{\sqrt{a^5}*\sqrt{b^{10}}}$

11. Rosie123

12. mathslover

ok ! $\huge{\sqrt{a^5}*\sqrt{(b^5)^2}}$ @King please help rosie further have to go

13. mathslover

I will post the solution tomorrow if king will not be able to help u

14. King

ok

15. Rosie123

thanks a lot :)

16. King

will help... @Rosie123 hav u understood what mathslover has explained

17. Rosie123

yes

18. King

ok nw u see $\sqrt{(b ^{5})^{2}}$

19. King

hw will u simplify this further,i.e,take out the root....

20. Rosie123

of b^2?

21. King

yeah of (b^5)^2

22. Rosie123

so do u just cross out 5 on a and b?

23. King

no only b since a does not have the extra whole squared... see, a is root a^5 but b is root (b^5)^2

24. King

for a^5 u can simplify further into $\sqrt{a ^{2}}\times \sqrt{a^2}\times \sqrt{a}$

25. King

hav u solved it?

26. Rosie123

|dw:1341161053035:dw|ok so answer can be a^2b^5 Sqrt a

27. King

yes wonderful!!! :D

28. Rosie123

ok i got it thank you so much :)

29. King

yw!!
