Exponent Rules Examples
Example 1: What is the simplification of 73 × 71?
Solution:
73 × 71 = 73+1 = 74
Example 2: Simplify and find the value of 102/52.
Solution:
We can write the given expression as;
102/52= (10/5)2 = 22 = 4
Example 3: Find the value of (256)3/4
Solution:
(256)3/4 = (44)3/4 = 44×(3/4) = 43 = 64
Example 4: Find the value of 7-3
Solution:
7-3 = (1/7)3 = 13/73 = 1/343
Example 5: Find the value of x if 125 = 25/5x
Solution:
We have 125 = 25/5x
⇒ 53 = 52/5x
⇒ 53 = 52-x
Now the quantity is the same on both sides and bases are also the same, hence, exponents will also be the same.
⇒ 3 = 2-x
⇒ x = 2-3 = -1

Laws of Exponents
Laws of Exponents: Exponents are a way of representing very large or very small numbers. Exponent rules are the laws of the exponents that are used to solve various exponents’ problems. The multiplication, division, and other operations on exponents can be achieved using these laws of exponents. There are different rules of exponents also called laws of exponents in Mathematics and all these laws are added in the article below.
In this article, we will learn about Exponents Definition, Laws of Exponents, Laws of Exponents Examples, and others in detail.
