# Express each of the following prducts as a monomials and verify the result in each case for x=1:

Evaluate for x = 2.5 and y=1.

Answer :

-8 × - 20 × x^{2} × x × y^{6} × y

= 160x^{3}y^{7}

Verify:

When, x = 2.5 and y = 1

R.H.S = 160x^{3}y^{7}

= 160 × (2.5)^{3} × (1)^{7}

= 2500

L.H.S = - 8 × 2.5^{2} × 1 × -20 × 1 × 2.5

= 2500

Therefore,

L.H.S = R.H.S
