Step by step solution :
Step 1 :
Equation at the end of step 1 :
(4 • (x2)) 7y
—————————— • ————————
5y (22•3x4)
Step 2 :
7y
Simplify ————————
(22•3x4)
Equation at the end of step 2 :
(4 • (x2)) 7y
—————————— • ————
5y 12x4
Step 3 :
Equation at the end of step 3 :
22x2 7y
———— • ————
5y 12x4
Step 4 :
22x2
Simplify ————
5y
Equation at the end of step 4 :
4x2 7y
——— • ————
5y 12x4
Step 5 :
Dividing exponential expressions :
5.1 x2 divided by x4 = x(2 - 4) = x(-2) = 1/x2
Canceling Out :
5.2 Canceling out y as it appears on both sides of the fraction line
Final result :
