You put the numbers you want to compare in a line with a space in the middle. the put

if the left is bigger and

if the right side is bigger.
8 maybe? I’m really not sure but I just did 5x1.6
About miles.
Subtract the flat rate of 1.75 from the spending limit of 10$ which leaves you with 8.25 then divide the rest of your spending money (8.25$) into your rate per mile (0.65) , so essentially , 8.25 / 0.65 which leaves you with the answer of ;
12 miles.
From the problem :

In multiplying expressions with the same bases, the exponent will be added accordingly.
For example :

the exponent of a are m and n, and the product will be a raised to the sum of m and n.
Applying this to the problem, we have :

The answer is d. 6^-1
Examples :
(-2)^3 = (-2)(-2)(-2) = - 8
(-3)^4 = (-3)(-3)(-3)(-3) = 81
(-1)^5 = (-1)(-1)(-1)(-1)(-1) = -1
** if the exponent is an even number, the answer will be positive. if the exponent is an odd number, then the answer will be negative
** but keep in mind....if the negative is not included with the base..
-(5^2) = - 25....but (-5^2) = 25
