Express each of the following prducts as a monomials and verify the result in each case for x=1:
Write down the product of 8x2y6 and-20xy verify the product for x=2.5, y=1
-8 × -2 × x2 × x × y6 × y
= 16 × x3 × y7
= 16x3y7
Verification is when, x = 2.5 and y = 1
R.H.S = 16 (2.5)3 × (1)7
= 16 × 15.625
= 250
L.H.S = -8 × 2.52 × 16 × -20 × 1 × 2.5
= 250
Therefore,
L.H.S = R.H.S
