Question

Use complete sentences to describe how logarithms can aid in difficult calculations.

Answer 1

Answer:

Step-by-step explanation:

Logrithms make calculations especially very large or very small numbers very easily

In log multiplication becomes addition and division becomes subtraction.

Also when we use log to base 10, we can make any number to the power of 10 and find log easily.

For example if we want to calculate 2329x5265/31500

We can do this by taking log.

log 2329+log 5265-log 31500 is calculated and for this anti log is calculated to get the answer

Similarly cube root of 2500 is to be done we find 1/3 log 2500 and take antilog .

Thus difficult calculations are made very easy

Answer 2

First, it is to be understood that logarithms allow a person to subject a number as an exponent of a base. As an example of ways in which logarithm is used to aid us in difficult calculations is when we calculate for the pH of a substance which has a formula of,
                                       pH = -log[H+]
