Answer :
To express logarithmic equations in exponential form, we can use the basic property that relates logarithms and exponents: if [tex]\log_b A = C[/tex], then [tex]b^C = A[/tex]. Let's apply this to the given problems.
(a) Convert [tex]\log_2 16 = 4[/tex] to exponential form:
Here, the base [tex]b = 2[/tex], the logarithm equals [tex]C = 4[/tex], and inside the log [tex]A = 16[/tex].
Using the property, we write:
[tex]2^4 = 16[/tex]
So, [tex]A = 4[/tex] and [tex]B = 16[/tex]. This means:
- [tex]A = 4[/tex]
- [tex]B = 16[/tex]
(b) Convert [tex]\log_5 3125 = 5[/tex] to exponential form:
Here, the base [tex]b = 5[/tex], the logarithm equals [tex]C = 5[/tex], and inside the log [tex]A = 3125[/tex].
Using the property, we write:
[tex]5^5 = 3125[/tex]
So, [tex]C = 5[/tex] and [tex]D = 3125[/tex]. This means:
- [tex]C = 5[/tex]
- [tex]D = 3125[/tex]
By understanding how to express logarithms in exponential form, you can make it much easier to solve problems involving growth, decay, and other exponential models.
