In representation of 2 to the power of n, what is n called?
Exponent
If n is a positive integer and x is any real number, then xn corresponds to repeated multiplication
xn=(x×x×.............×x)[n times]
We can call this “x raised to the power of n,” “x to the power of n”, or simply “x to the n.” Here, x is the base and n is the exponent or the power.
In representation of 2n, hence 2 is the base and n is the exponent.
