1.	Express each of the following products as a monomials and verify the result in each case for x=1:Evaluate (3.2x6y3) x (2.1x2y2) when x=1 and y=0.5
Answer» 3.2 × 2.1 × x⁶ × x² × y³ × y² = 6.72 × x⁸ × y⁵ = 6.72x⁸y⁵ Verify: When x = 1 and y = 0.5 R.H.S = 6.72x³y⁵ = 6.72 × 1⁸ × 0.5⁵ = 0.21 L.H.S= 3.2 × 1⁶ × (-.5)³ × 2.1 × 1² × 0.5²= 0.21 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 (3.2x6y3) x (2.1x2y2) when x=1 and y=0.5

Answer»

3.2 × 2.1 × x⁶ × x² × y³ × y²

= 6.72 × x⁸ × y⁵

= 6.72x⁸y⁵

Verify:

When x = 1 and y = 0.5

R.H.S = 6.72x³y⁵

= 6.72 × 1⁸ × 0.5⁵

= 0.21

L.H.S= 3.2 × 1⁶ × (-.5)³ × 2.1 × 1² × 0.5²= 0.21

Therefore,

L.H.S = R.H.S
