Introduction

In mathematics, simplifying expressions is a crucial skill that helps us solve problems efficiently and accurately. When dealing with exponents and fractions, simplification can be a bit challenging, but with the right techniques and strategies, it becomes a breeze. In this article, we will explore how to simplify exponents and fractions, using real-world examples and step-by-step explanations.

Simplifying Exponents

Exponents are a shorthand way of writing repeated multiplication. For example, 232^3 means 2×2×22 \times 2 \times 2. When simplifying exponents, we can use the following rules:

  • Product of Powers Rule: When multiplying two or more powers with the same base, we add the exponents. For example, 23×24=23+4=272^3 \times 2^4 = 2^{3+4} = 2^7.
  • Power of a Power Rule: When raising a power to another power, we multiply the exponents. For example, (23)4=23×4=212(2^3)^4 = 2^{3 \times 4} = 2^{12}.
  • Quotient of Powers Rule: When dividing two or more powers with the same base, we subtract the exponents. For example, 25÷23=25−3=222^5 \div 2^3 = 2^{5-3} = 2^2.

Let's apply these rules to the given problems:

1. a) 85÷838^5 \div 8^3

Using the Quotient of Powers Rule, we can simplify this expression as follows:

85÷83=85−3=82=648^5 \div 8^3 = 8^{5-3} = 8^2 = 64

1. b) 212÷292^{12} \div 2^9

Using the Quotient of Powers Rule, we can simplify this expression as follows:

212÷29=212−9=23=82^{12} \div 2^9 = 2^{12-9} = 2^3 = 8

1. c) 364÷364364 \div 36^4

First, let's simplify the denominator using the Product of Powers Rule:

364=(362)2=(62)2=6436^4 = (36^2)^2 = (6^2)^2 = 6^4

Now, we can rewrite the expression as:

364÷364=364÷64364 \div 36^4 = 364 \div 6^4

To simplify this expression, we can divide the numerator and denominator by 636^3:

364÷64=36463÷61=36463×16=36464364 \div 6^4 = \frac{364}{6^3} \div \frac{6}{1} = \frac{364}{6^3} \times \frac{1}{6} = \frac{364}{6^4}

Now, we can simplify the fraction by dividing the numerator and denominator by 636^3:

36464=364÷6364÷63=364÷636=36463×6=36464\frac{364}{6^4} = \frac{364 \div 6^3}{6^4 \div 6^3} = \frac{364 \div 6^3}{6} = \frac{364}{6^3 \times 6} = \frac{364}{6^4}
