A^-b is the same as 1/a^b.
When there is a negative power, place the number and power over 1.
a^b/a^c = a^(b-c).
c is a negative power, because it is being divided, and is underneath b, which is a positive (and so it stays in the numerator).
a^c/b^c = (a/b)^c
Inside this one, the power of c is distributed to all numbers inside the parenthesis, in this case a and b.

Step-by-step explanation:

Answer:
%40
Step-by-step explanation:
<u>Step 1: Divide 2/5</u>
2/5 = 0.4
<u>Step 2: Convert to Decimal by multiplying by 100</u>
0.4 * 100 = %40
Answer: %40
3x-2=-x-6
do the inverse and add 2 to the whole number on the other side which is -6
3x=-x-4
do the inverse with the variable -x and add x to 3x
4x=-4
divide -4/4 since the inverse of multiplication is division
x=-1
