Name Evaluating Numerical Expressions with Exponents- Step-by-Step Lesson Lesson 1 Exponent Problem: Write the expression as an exponent. 4 x 4 x 4 x 4 x 4 Explanation: The exponent of a number shows you how many times the number is being multiplied by itself. The number of times it is multiplied by itself is written as a small number to the right and above the base number. This number (4) is being multiplied by itself 5 times, so it will be written as: 4 5 In this: 4 5 = 4 4 x 4 x 4 x 4 = 1024 Other names for an exponent are an index or a power.

Name Evaluating Numerical Expressions with Exponents- Guided Lesson Explanation Explanation#1 The exponent of a number tells you how many times it should be multiplied by itself. In 6 5 the "5" says to multiply 6 by itself 5 times, so 6 5 = 6 6 x 6 x 6 x 6 = 7776 So, the answer is 7776. Explanation#2 The exponent of a number tells you how many times it should be multiplied by itself. In 7 4 the "4" says to multiply 7 by itself 4 times, so 7 4 = 7 7 x 7 x 7 = 2,401 In 9 6 the "6" says to multiply 9 by itself 6 times, so 9 6 = 9 9 x 9 x 9 x 9 x 9 = 531,441 Step 3) Now we can add this number. 2,401 + 531,441 = 533,842 So, the answer is 533,842. Explanation#3 Using the same concept we find the value of each number and then calculate the difference. In 8 4 the "4" says to multiply 8 by itself 4 times, so 8 4 = 8 8 x 8 x 8 = 4096 In 3 7 the "7" says to multiply 3 by itself 7 times, so 3 7 = 3 3 x 3 x 3 x 3 x 3 x 3 = 2187 Step 3) Now we can subtract this number. 4096-2187 = 1909 So, the answer is 1909.
