1.	Express each of the following products as a monomials and verify the result in each case for x=1:Find the value of (5x6) x (-1.5x2y3) x (-12xy2) when x = 1,y=0.5
Answer» 5 × -1.5 × -12 × x⁶ × x² × x × y³ × y² = 90 × x⁹ × y⁵ = 90x⁹y⁵ Verification: x = 1 and y = 0.5 R.H.S = 90x⁹y⁵ = 90 (1)⁹ (05)⁵ = 2.8125 L.H.S = 2.8125 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:Find the value of (5x6) x (-1.5x2y3) x (-12xy2) when x = 1,y=0.5

Answer»

5 × -1.5 × -12 × x⁶ × x² × x × y³ × y²

= 90 × x⁹ × y⁵

= 90x⁹y⁵

Verification:

x = 1 and y = 0.5

R.H.S = 90x⁹y⁵

= 90 (1)⁹ (05)⁵

= 2.8125

L.H.S = 2.8125

Therefore,

L.H.S = R.H.S
