For logarithmic equations,
log
b ( x ) = y
logb(x)=y
is equivalent to b y = x
by=x
such that x > 0
x>0 , b > 0
b>0 , and b ≠ 1
b≠1
.In this case, b = 5
b=5 , x = 25
x=25 , and y 2
y=2 .
b = 5
b=5
x =
25
x=25
y = 2
y=2
Substitute the values of b
b , x
x , and y
y
into the equation
b y =
x
by=x
.

25
