I have 2 questions the first I have narrowed down to 2 possible solutions the second has 3. What is the solution to log sub 5 (2x+3)=2 a)13/2 or b)14? The next problem f(x)= log sub 5 x what is the value of 1/25? a)square root of 2 b)-1/2 or c)1/2?

Question

Help is greatly appriciated.

im great at math so for the 1st question it's a.13/2.and for 2nd question its a.a square root of 2

In log base 5, the value of 25 is 2. The value of 1/25 is -2

ie; 5^(-2)= 1/25
