Find the product:(7/2)x2((4/7)x + 2)

1.	Find the product:(7/2)x2((4/7)x + 2)
Answer» (7/2)x²((4/7)x + 2) Let p, q and r be three monomials. Then, by distributive law of multiplication over addition, we have: P × (q + r) = (p × q) + (p × r) Now, = ((7/2)x² × (4/7)x) + ((7/2)x² × 2) = ((7×4)/ (2×7))x³ + ((7×2)/(2×1))x² … [∵ a^m × aⁿ = a^m+n] = ((1×2)/ (1×1))x³ + ((7×1)/(1×1))x² = (2)x³ + (7)x²

Answer»

(7/2)x²((4/7)x + 2)

Let p, q and r be three monomials.

Then, by distributive law of multiplication over addition, we have:

P × (q + r) = (p × q) + (p × r)

Now,

= ((7/2)x² × (4/7)x) + ((7/2)x² × 2)

= ((7×4)/ (2×7))x³ + ((7×2)/(2×1))x² … [∵ a^m × aⁿ = a^m+n]

= ((1×2)/ (1×1))x³ + ((7×1)/(1×1))x²

= (2)x³ + (7)x²
