1. Kreshnik

$\Large \sqrt[m]{a^n}=a^{\frac{n}{m}}$

2. Kreshnik

$\LARGE \sqrt{x}=x^{\frac12}$

3. yrivers36

ok thank you. I forgot about that

4. cwrw238

no unless x = 1

5. yrivers36

so then if I have a problem like

6. yrivers36

|dw:1333375554625:dw|

7. yrivers36

that would not be

8. yrivers36

|dw:1333375584684:dw|

9. Kreshnik

|dw:1333375680517:dw|

10. yrivers36

ok so there i just break problem down before finding solution

11. cwrw238

|dw:1333375647733:dw|

$\LARGE \sqrt[2]{y^2}=y^{2/2}=y^1=y$ when we write $\LARGE \sqrt y$ there's number two in square root, but we don't write it !
