Please help me simplify these expressions

Step-by-step explanation:

If base of variable is same, add the powers

1) x² * x * x³ * x⁵ = x²⁺¹⁺³⁺⁵ = x¹¹

2) -2n² * -n⁴ * 5n³ = (-2* -1*  5 ) *n²⁺⁴⁺³ = 10n⁹

3)-3x⁴ * 2x⁵ * - x = (-3 * 2 * -1)* x⁵⁺⁴⁺¹ = 6x¹⁰

1.     2. 10   3.  6

Step-by-step explanation:

1.  

Imagine the expression is written like this:

(x)(x) *  (x)  * (x)(x)(x) * (x)(x)(x)(x)(x)

Simply add up the number of x's and have that number be the exponent.

There are 11 x's, so it will be

2. 10

Do the same as above, but this time remember that two negatives equal a positive.

10

3. 6

Again, two negatives equal a positive.

-3 x 2 x -1 = 6

Do the same as the above two.

6

the answer is a beach is the best place to be
