The exponential expression is given as 3⁴. Option B
Index form, also known as exponential form, is a mathematical notation used to represent numbers using exponents. It involves expressing a number as a base raised to a certain power.
From the information given, we have that the expression is given as;
3⋅3⋅3⋅3
Now, we can see that this is a repetition of values and index forms make us understand that these numbers can be written in smaller forms.
Then, we have the expression as;
3⁴
