Question

find the product (a) (x^2+3xy) (4x)
(b) 9pqr(2p^2q - 3q^2r)
(c) 3/4a^2(2/3b^2+8ab)​

Answer 1

1.)(x²+3xy)(4x)=4x³+12x²y

2.)9pqr(2p²q-3p²r)=18p³q²r-27p³qr²

3.)3/4a²(2/3b²+8ab)=6/12a²b²+24ab/4a³b

=1/2a²b²+6/a².

Answer 2

Step-by-step explanation:

a) (x^2+3xy)(4x) = (4x^3+12x^2y)

b) 9pqr(2p^2-3q^2r) = 18p^3q^2r -27pq^3r^2

c).....
