Percent relative error is calculated by the formula: (experimental value - literature value/ experimental value) x 100%
Therefore, (6-7/7) x 100% = 14.3%
Your answer is in absolute value :)
For this case we must resolve the following expression:
We have to:

The base change rule can be used if a and b are greater than 1 and are not equal to x.
We substitute the values in the base change formula, using
