Answer:
Percent change = 5.4%
Step-by-step explanation:
Given:
Number of students voted last year = 762
Number of students voted this year = 721
Change in the number of students who voted from last year to this year is given by the difference of their number. This gives,
Change in the number of students that voted = 762 - 721 = 41
Now, percentage change in the number of students that voted is given as:
Therefore, the percent change in the number of students that voted is 5.4%.

Answer:
3 log (z) - 1/2log (x) - 1/2 log (5) -1/2 log y
Step-by-step explanation:
log(z3)/√x5y)
= log (z3) - log (√x5y) [division being subtracted]
= 3 log (z) - {log (√x) + log (√5y)} [ multiplication being added in the denominator]
= 3 log (z) - {log (x)^1/2 + log (5)^1/2+ log (y)^1/2}
= 3 log (z) - 1/2{log (x) + log (5)+ log y }
We can solve inside the curly bracket and then multiply with 1/2 or we can solve it separately
= 3 log (z) - 1/2log (x) - 1/2 log (5) -1/2 log y
How does this work?
1) any two terms being multiplied in logarithms are added with the log of each.
2) the exponent becomes the co- efficient.
3) any two terms being divided in logarithms are subtracted with the log of each
