Question 1

In the following question, out of the four options, only one is correct. Write the correct answer:

In $2^n,$ n is known as :
(a)Base
(b)Constant
(c)Exponent
(d)Variable

Answer 1

We know that $a^n$ is called the nth power of a, and is also read as ' a raised to the power n'. The rational number 'a' is called the base and 'n' is called the exponent (power or index).
In the same way in $2^n$ 'n' is known as the exponent.
