Find the product:8a2(2a + 5b)

1.	Find the product:8a2(2a + 5b)
Answer» 8a²(2a + 5b) 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, = (8a² × 2a) + (8a² × 5b) = (16a³ + 40a²b) … [∵ a^m × aⁿ = a^m+n]

Answer»

8a²(2a + 5b)

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,

= (8a² × 2a) + (8a² × 5b)

= (16a³ + 40a²b) … [∵ a^m × aⁿ = a^m+n]
