Step-by-step explanation:

Changes made to your input should not affect the solution:

(1): "y4"   was replaced by   "y^4".  1 more similar replacement(s).

STEP

1

:

           y4

Simplify   ——

           y

Dividing exponential expressions :

1.1    y4 divided by y1 = y(4 - 1) = y3

Equation at the end of step

1

:

 y3

 ——

 y4

STEP

2

:

           y3

Simplify   ——

           y4

Dividing exponential expressions :

2.1    y3 divided by y4 = y(3 - 4) = y(-1) = 1/y1 = 1/y

Final result :

 1

 —

 y

any more help just ask :)
