I guess the original expression is 125 = 5^x
If you apply logarithms to both sides, you get:
log (125) = x * log (5) <----------- logaritmic equation
=> x = log (125) / log(5)
Given that 125 is 5^3
you can simplify to
x = log (5^3) / log(5) = 3 log (5) / log (5) = 3 * 1 = 3
There you have the expression as a logarithmic equation and the solution of the equation.

Answer:
the function f(x) = x + 1 adds 1 to any value you feed it. You give it a 5, this function will give you a 6: f(5) = 5 + 1 = 6. Functions do have a criterion they have to meet, though. And that is the x value, or the input, cannot be linked to more than one output or answer.
Step-by-step explanation:
we could define a function where the domain X is again the set of people but the codomain is a set of number. For example , let the codomain Y be the set of whole numbers and define the function c so that for any person x , the function output c(x) is the number of children of the person x.
hop u get it
The length of UV is 11.
Solution:
UV = 2x - 13
VW = -18 + 2x
UW = 17
UV + VW = UW
2x - 13 - 18 + 2x = 17
4x - 31 = 17
Add 31 on both sides.
4x - 31 + 31 = 17 + 31
4x = 48
Divide by 4 on both sides.
x = 12
UV = 2x - 13
= 2(12) - 13
= 24 - 13
UV = 11
The length of UV is 11.
