The definition of a logarithm says :
log
b
x
=
y
⇔
b
y
=
x
In other words you can say that logarithm is the exponent to which you must raise the base
(
b
)
to get number
x
.
In this case
x
is the exponent to which you have to raise base (5) to get 625
5
x
=
625
This is the exponential form.
To find the answer you have to count which power of 5 is 625
5
1
=
5
5
2
=
5
⋅
5
=
25
5
3
=
25
⋅
5
=
125
5
4
=
125
⋅
5
=
625
5
4
=
625
so
x
=4
