-2,8 i pretty sure. But if it’s not then...
Answer:
D. -1/2
Step-by-step explanation:
First to rewrite the equation in numbers

First, we need to find what exponent would get 1/25 to 125.

Sense 1/25 is a fraction we must use a negative exponent to make it a whole number. We can just find what exponent would get 25 to 125 then make it negative. 1 wouldn't be enough and 2 would be too much so y is between 1 and 2 into negative is between -1 and -2. Sense the original equation has (y-1) the only option you can subtract 1 from to get between -1 and -2 is -1/2 which would give -1 1/2.
Consider the number 50,540.We have to determine the significant figure.
Significant figures are the digits that carry meaning contributing to its measurement resolution. It excludes the leading and trailing zeroes.
The first zero in the 50 is considered to be a significant number, while the second zero (in the 540) is not significant number.
The second zero is a called a placeholder zero. It can be removed by converting the number into scientific notation.
