Question

Which logarithmic equation is equivalent to the exponential equation below? 70.81 = ea

Answer 1

Answer:

$ln 70.81 =a$

Step-by-step explanation:

Given is an equation in variable a as

$70.81=e^a$

Since log and exponential are inverses of each other we can convert the given exponential equation into log equation

Taking log to base e on both the sides we get

$log_e 70.81 =a$

This is the equivalent logrithmic equation

This can also be written as$ln 70.81 =a$

Answer 2

Loge 70.81 = a
Log to the base e is also  written as ln
ln 70.81 = a
