Question

I need help with this

Answer 1

The answer is the first one

Answer 2

Answer:

it's 2.) -12x^8

Step-by-step explanation:

When you're multiplying two different expressions with different exponents but the same variable, you do the same thing you normally would when multiplying numbers, but you add the exponents together.

So your problem is -6x^3 * 2x^5

First step is to ignore the exponent and multiply the base numbers together:

-6 * 2

= -12

** And normally, if the two numbers just have the variable (x)  you multiply them together, and you'd get a number times x^2. And the reason this happens is bc there is always an invisible 1 exponent above a variable and you add the 1's together to make the square. When

Now add the variables and exponents (make sure to add your exponents together )

x^3+x^5

= x^8

Put your answer together add you get:

-12x^8
