Question

does anyone know how to do this HELP !!!

Answer 1

Simple....
1) $-m^{4} n^{-5}$--->>$-\frac{ m^{4} }{ n^{5} }$
3) $2y x^{-5}$--->> $\frac{2y}{ x^{5} }$
5)$3 x^{3} y^{-5}$--->> $\frac{3 x^{3} }{ y^{5} }$
7)$4 x^{-5} y^{2}$-->> $\frac{ 4y^{2} }{ x^{5} }$
9)$4x^{-3} y^{5}$--->>$\frac{ 4y^{5} }{ x^{3} }$
11)$-5u^{-3} v^{0}$--->>$- \frac{5}{ u^{3} }$
Thus, the answers to all your problems.. :D

Answer 2

Hi

1) -m^4n^-5= -m^4n^5

2) -4x^-1y^3= -4y^3/x

3) 2yx^-5= 2y/x^5

4) 3nm^-4=3n/m^4

5) 3x^3y^-5=3x^3/y^5

6) -5m^0n^-2= -5/n^2

7) 4x^-5y^2= 4y^2/x^5

8) 2m^-3n^4= 2m^3n^4

9) 4x^-3y^5= 4y^5/x^3

10) 2m^-1= 2/m

11) -5u^-3y^0= -5/u^3

12) -x^-2y^4= -y^4/x^2

Finally :)

I hope that's help and good luck !
