(3x^2)(4x^7) And explain why please. So i know I have to add the exponents and multiply the coefficients. But when you multiply 2 x's they become squared right?

Best ResponseYou've already chosen the best response.0If you had 2 x's multiplied together it would be x squared. But you already have an x squared (2 x's) if you multiply those two by 7 more, you'll have 9 x's multiplied together (x^9)

Best ResponseYou've already chosen the best response.0Then it's just a matter of multiplying the nonvariable part (3)(4) = 12

Best ResponseYou've already chosen the best response.0you can think of it as if the x is x^1 then if you've got x*x it's like you have x^1*x^1 there for what you get is x^2

Best ResponseYou've already chosen the best response.0When you multiply 2 \(x\)s together, you're adding the exponents just like normal. The variable \(x\) is the same as \(x^1\). So when you multiply \(x\) by \(x\), you're really multiplying \(x^1\) by \(x^1\). When you add the exponents, you get \(x^2\).
