## marigirl one year ago Having a blank moment.. please help me write square root of u on the top line

1. marigirl

$\frac{ 2u-1 }{ \sqrt{u} }$

2. marigirl

does it become (2u-1)(u)^(-0.5)

3. Compassionate

Do you want o solve for u?

4. marigirl

i want to bring square root of u to the top

5. marigirl

$\frac{ 2u-1 }{ \sqrt{u} }=2u-2*x ^{\frac{ -1 }{ 2 }}$

6. marigirl

is that correct?

7. marigirl

i mean 2u-1

8. Compassionate

$\frac{ (2u-1^{(0.05u)} }{ 1 }$

9. marigirl

omg i cant do that....because its a relationship at the top!!!!!! opps

10. anonymous

(2u−1(0.05u)1

11. marigirl

$\frac{ 2u-1 }{ \sqrt{u} }=\frac{ 2u }{ \sqrt{u} }-\frac{ 1 }{ \sqrt{u} }$

12. zepdrix

If you multiply $$\rm \sqrt u$$ by $$\rm \sqrt u$$ will get rid of the square root down there :) ya?

13. zepdrix

$\large\rm \frac{(2u-1)}{\sqrt{u}}\cdot\color{royalblue}{\frac{\sqrt u}{\sqrt u}}$Gotta do this fancy business

this is ok because your effectively multiplying by 1
