Question

Multiply -8/21x2y3 by -7/16xy2 and verify your result for x=3 and y =2​

Answer 1

GIVEN:

Value of x= 3 and y= 2

EQUATION:

• -8/21x2y3. --------------(1)
• -7/16xy2. --------------(2)

Now putting values of x and y

in equation (1)

-8/21×3×2×2×3 = -36/21 = 41 (approx)

Now putting values of x and y

in equation (2)

-7/16×3×2×2 = -84/16 = 6 (approx)

now, multiplying both the equations:

41×6 = 246
