Consider this solution:
1) formula of volume is   V= \frac{4}{3} \pi r^3, where \ r - radius
2) if new_r=2r, then the formula is   new_V= \frac{4}{3}*(2r)^3= \frac{4}{3} \pi *8r^3=8*( \frac{4}{3} \pi r^3)
3) new_V/V=8:1
The volume increases by 8 times.

The first answer of the missing blank is 4/5.

The second answer of the missing blank is 2.

The third answer of the missing blank is 25.

*For all of these solutions, I will be using the common rules for logarithms.*

Solution for the first question:

Log9^4/5 must equal log9^4-log9^5, or it could also equal the more proper version, which is simplified: 2log9^2-log9^5.

Solution for the second question:

Log3^22 must equal log3^11+log3^2, if you break it down.

Solution for the third question:

Log9^25 must equal 2log9^5 because it will be like this when simplifying it:

log9^25=2log9^5

log9^5²=2log9^5

2log9^5=2log9^5

These are all of the step-by-step procedures for all three of these given questions. Anyways, I hope that this helped you!
