<p>Exponent is used to indicate the number of times a base must be multiplied by itself. For example, in 2³ the exponent 3 tells us that base 2 must be multiplied by itself three times. Therefore, Therefore, 2³ = 2 × 2 × 2 = 8. We can also call the exponent the "power" of a number. So, 2³ can be read as "2 to the power of 3." Exponents can be of various forms; they can be whole numbers, fractions, negative values, or even decimals. This article will discuss exponents in detail.</p>
