1.	Express each of the following products as a monomials and verify the result in each case for x=1:Evaluate (-8x2y6) x (-20xy) for x = 2.5 and y=1.
Answer» -8 × -20 × x² × x × y⁶ × y = 160x³y⁷ Verify: When, x = 2.5 and y = 1 R.H.S = 160x³y⁷ = 160 × (2.5)³ × (1)⁷ = 2500 L.H.S = - 8 × 2.5² × 1 × -20 × 1 × 2.5 = 2500 Therefore, L.H.S = R.H.S

Express each of the following products as a monomials and verify the result in each case for x=1:Evaluate (-8x2y6) x (-20xy) for x = 2.5 and y=1.

Answer»

-8 × -20 × x² × x × y⁶ × y

= 160x³y⁷

Verify:

When,

x = 2.5 and y = 1

R.H.S = 160x³y⁷

= 160 × (2.5)³ × (1)⁷

= 2500

L.H.S = - 8 × 2.5² × 1 × -20 × 1 × 2.5

= 2500

Therefore,

L.H.S = R.H.S
