Step-by-step explanation:
how do we find area? Length x width, right?
Let's break up each part.
3x3y2 = 3(x)(x)(x)(y)(y)
5x2y3 = 5(x)(x)(y)(y)(y)
Combining everything we have, 3(5)(x)(x)(x)(x)(x)(y)(y)(y)(y)(y). That's 15x5y5.
We multiply the coeffiecients and add exponents with the same base.
Hope this helps!
