Question

Law of Exponent:
Simplify

(-7xy³) (2x²y)

Answer 1

When you multiply exponents you add them, so for example:

\[\huge (x^3)(x^5) \implies x^{3+5} = x^8\]

Answer 2

Now give your problem a shot and see what you get, if you still have trouble, ask.

Answer 3

ok

Answer 4

so the answer will be -5xy² ?

Answer 5

You just copy pasted something and it was wrong, actually try it yourself please.

Answer 6

've got this answer : I subtract -7 and 2 since they are opposite sign then I got -5 then I add the exponent of x then got x³ then I also add the exponent of y then it will be y^4 so in all this is my answer: -5 x^3 y^4 . is it correct?

Answer 7

No, why would you subtract when multiplying, what's -7*2?

Answer 8

ahh -14 x^3 y ^4 ?

Answer 9

Yes :)
