What is meant by a fraction?
A fraction is a part of a whole or, more broadly, any number of equal parts. In ordinary English, a fraction describes the number of components of a specific size and consists of a numerator displayed above a line (or before a slash like 12) and a non-zero denominator displayed below (or after) that line.
In addition to common fractions, numerators and denominators are used in rare fractions such as compound fractions, complex fractions, and mixed numerals.
Positive common fractions have natural integers as their numerator and denominator.
Here we need to find the value of n for which 9=(1/27)ᵃ⁺³
Now, we have to rewrite with a base of 3 we get,
3²=3⁻³.3ᵃ⁺³
2=-3(a+3)
2=-3a-9
=2+9=-3a
11=-3a
a=-11/3
Therefore, the values is a=-11/3
