Express each of the following products as a monomials and verify the result for x=1, y= 2:

× × 5 × x² × x⁴ × x × y⁴ × y² × y

= × x⁶ × y⁶

= x⁶y⁶

Verification:

When x = 1 and y = 2

R.H.S = × 1⁶ × 2⁶

= × 64

= 5 × 2

= 10

L.H.S = × 1² × 2⁴ × × 1⁴ × 2² × 1 × 2 × 5

= 10

Therefore,

L.H.S = R.H.S
