Question

Help?! Can somebody tell me the answer and can they explain how to do it?

Answer 1

Answer:

$15x^7y^5$

Step-by-step explanation:

Given

$5x^3y^2\times 3x^4y^3$

Rewrite it as

$(5\cdot 3)\times (x^3\cdot x^4)\times (y^2\cdot y^3)$

Use power property:

$a^m\cdot a^n=a^{m+n},$

so

$x^3\cdot x^4=x^{3+4}=x^7\\ \\y^2\cdot y^3=y^{2+3}=y^5$

Then

$(5\cdot 3)\times (x^3\cdot x^4)\times (y^2\cdot y^3)=15\times x^7\times y^5=15x^7y^5$
