1.	Express each of the following products 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
Answer» -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

Answer»

-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
