Question

Multiplying with Monomials 1) 2x^3y^3 ⋅ 3y^4 2) 3vu^2 * 3vu^2 3) yx^3 * x^3 * 3yx^4 4) 2x^2 y^2 * 4x^3 y^4 5) −8x^2(7x − 2)

Answer 1

1) The given expression is

2x^3y^3 ⋅ 3y^4

We would apply the rule of exponent shown below

a^b * a^c = a^(b + c)

Thus, we have

2x^3y^3 ⋅ 3y^4 = 2 * 3 * x^3 * y^(3 + 4)

= 6x^3y^7
