-4²
Any number repeatedly multiplied by itself has an exponent. so (-4)(-4) has an exponent of 2 while (-4)(-4)(-4) would have an exponent of 3 and be written as -4³.
Also extra tip: Negative numbers multiplied by a negative number will always be positive.
So :

?
First, you want to bring everything together on the top of the fraction.
12=24/2 so you can have

Add like terms -- 12 +24 = 36

Now we are at

Which is the lowest possible simplified version while remaining at exact value.
Feel free to check my math! I kinda did this off the top of my head.
Entire distance is
25/2(1+1/4+(1/4*1/2))
=25/2(1+1/4+1/8)
=25/2(8/8+2/8+1/8)
=25/2(11/8)
=275/16
=17 3/16 miles [assuming you need fractions as answers]
Answer: B. n ÷ 2
Step-by-step explanation: The number on the left side is the one being devided. so to awnser the question, it is N ÷ 2.
