Answer:
1. -18x¹¹
2. 3n⁷
Step-by-step explanation:
For these problems, there are two things you need to worry about: negative signs and exponents.
1. Let's look at the signs first. There is only one value with a negative sign, meaning that the negative sign will stay.
When multiplying with exponents, you have to add up the exponents. Don't forget the numerical coefficients.
-3x² · 3x · 2x³ · x⁵ = -18x¹¹
2. There are two negative signs in this probem, meaning that they will cancel out. Multiply the rest like we did in the first problem.
3n² · -n² · -n³ = 3n⁷
