Answer:

n¹³

Step-by-step explanation:

Division and multiplication have the same priority in pemdas, so you can solve this by dividing/multiplying from left to right.

Also remember that when dividing exponents of the same base, you subtract them, and when multiplying, you add them.

n⁶· n⁵ · n⁴ ÷ n³ · n² ÷ n

= (n⁶· n⁵) · n⁴ ÷ n³ · n² ÷ n

= (n¹¹ · n⁴) ÷ n³ · n² ÷ n

= (n¹⁵ ÷ n³) · n² ÷ n

= (n¹² · n²) ÷ n

= n¹⁴ ÷ n

= n¹³

Ultimately you just have to calculate

6 + 5 + 4 - 3 + 2 - 1 = 13

Ad libitum [116K]

The answer is B)x+y=y+x.

This is just changing the order of the numbers to get the same equation....\

So for example if I have 2+7 and I use the property of addition It would give me 2+7=7+2.

Pls mark brainliest if this helped!
