Question

a) 5xy ×? = 15x²y² can someone explain​

Answer 1

Answer:

$5xy*3xy=15x^2y^2$

Step-by-step explanation:

Multiply 5*3 to get 15, and each x and y is squared, so 5xy needs another set of x and y to have two xs and ys in the final expression, so you multiply $5xy$ by $3xy$ to get your answer.
