To calculate the antilogarithm (antilog) of a number, we reverse the logarithm operation. When you see "antilog," it typically means using the base 10 by default, unless otherwise specified.

Given the number $1.42e1$, it is represented in scientific notation as:

$1.42 \times 10^1 = 14.2$

The antilogarithm of $14.2$ in base 10 is calculated as:

$\text{antilog}_{10}(14.2) = 10^{14.2}$

Let's compute this value.The antilogarithm of $1.42e1$ (or 14.2) in base 10 is approximately:

$\text{antilog}_{10}(14.2) \approx 1.584 \times 10^{14}$

2. How do you compute antilogarithms in different bases?
3. What is the relationship between logarithms and exponents?
4. How does the natural antilogarithm differ from the base 10 antilogarithm?

Tip: Remember that the antilogarithm is the inverse operation of a logarithm, meaning it "undoes" the logarithm.
