1 / 5^-2
First, let's work out the denominator.
5^ -2 = 1/25. When an exponent is negative, it means to put a 1 over the product. Like we did earlier.
Now we have 1 / (1/25).
1 / (1/25)
Divide 1 by 25.
1 / 0.04
Divide 1 by 0.04
25
The answer is 25!

Answer:
1. Yes 2. No 3. Yes 4. No
Step-by-step explanation: 1 is a function because none of the x values repeat, 2 isn't a function because in the x coordinates, -2 repeats, 3 is a function because if you were to draw a (vertical) line through each point, none of them have two points on one line, 4 is a function because none of the x coordinates point to more than one y coordinate

Answer:
3 ln(1-x) - 3 ln3 - 3 ln x
Step-by-step explanation:
We have the following logarithmic expression.
ln(1-x/3x)³
We apply the logarithm power rule.
3 ln(1-x/3x)
We apply the logarithm quotient rule.
3. [ln(1-x) - ln 3x]
We apply the logarithm product rule.
3. [ln(1-x) - (ln3 + ln x)]
3. [ln(1-x) - ln3 - ln x]
We apply the distributive property.
3 ln(1-x) - 3 ln3 - 3 ln x
