Find the product:10a2(0.1a – 0.5b)

1.	Find the product:10a2(0.1a – 0.5b)
Answer» 10a²(0.1a – 0.5b) Let p, q and r be three monomials. Then, by distributive law of multiplication over subtraction, we have: P × (q – r) = (p × q) – (p × r) Now, = (10a² × 0.1a) – (10a² × 0.5b) = (1a³ – 5a²b) … [∵ a^m × aⁿ = a^m+n]

Answer»

10a²(0.1a – 0.5b)

Let p, q and r be three monomials.

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

P × (q – r) = (p × q) – (p × r)

Now,

= (10a² × 0.1a) – (10a² × 0.5b)

= (1a³ – 5a²b) … [∵ a^m × aⁿ = a^m+n]
