NC6EE1 Lesson 5 Flashcard Write/Evaluate Expressions With Exponents

Front

What is an exponent?

Back

An exponent is a mathematical notation indicating the number of times a number (the base) is multiplied by itself. For example, in the expression 2^3, 2 is the base and 3 is the exponent, meaning 2 is multiplied by itself 3 times (2 * 2 * 2).

Front

How do you evaluate an expression with exponents?

Back

To evaluate an expression with exponents, calculate the value of the base raised to the exponent first, then perform any additional operations (like addition, subtraction, multiplication, or division) as indicated in the expression.

Front

What is the value of 2^5?

Back

The value of 2^5 is 32, since 2 multiplied by itself 5 times equals 32 (2 * 2 * 2 * 2 * 2).

Front

What is the value of 3^2?

Back

The value of 3^2 is 9, since 3 multiplied by itself equals 9 (3 * 3).

Front

What is the result of the expression 2^5 - 3^2?

Back

The result of the expression 2^5 - 3^2 is 23, since 32 - 9 equals 23.

Front

How do you simplify the expression (2^3 * 3^2) - 5?

Back

First, calculate 2^3 = 8 and 3^2 = 9. Then multiply them: 8 * 9 = 72. Finally, subtract 5: 72 - 5 = 67.

Front

What is the value of 4^2?

Back

The value of 4^2 is 16, since 4 multiplied by itself equals 16 (4 * 4).

Front

How can you express 3 * 3 * 3 * 3 using exponents?

Back

You can express 3 * 3 * 3 * 3 as 3^4, indicating that 3 is multiplied by itself 4 times.

Front

What is the base in the expression 5^3?

Back

The base in the expression 5^3 is 5, which is the number being multiplied by itself.

Front

What does it mean to evaluate an expression?

Back

To evaluate an expression means to calculate its value by performing the operations indicated in the expression.
