# Rational Exponents

In mathematics, exponent of a number tells how many times a number is multiplied by itself. Exponent can be whole number, integer or fractional.

An exponential expression in general would look as follows: b$^x$. Here, the â€˜bâ€™ is called the base and the x is called the exponent.

The exponent refers to the number of times the base is multiplied to itself.

The exponent refers to the number of times the base is multiplied to itself.

**For Example:**2$^3$=2*2*2We see that since the exponent in the above example is 3, the 2 is multiplied to itself three times. Similarly if we have 3$^4$ that it would be equal to 3*3*3*3.

However these exponents are not restricted to positive integers only. The exponents can be negative and they can be fractions as well (proper or improper). In other words, the exponents can be rational numbers as well.
