Exponents and Order of Operations Assessment

Front

What is an exponent?

Back

An exponent is a number that shows how many times to use the base in a multiplication. For example, in 2^3, 2 is the base and 3 is the exponent.

Front

What does the order of operations refer to?

Back

The order of operations is a set of rules that determines the sequence in which calculations are performed in a mathematical expression. The common acronym is PEMDAS: Parentheses, Exponents, Multiplication and Division (from left to right), Addition and Subtraction (from left to right).

Front

Calculate: 3^2 + 4^2

Back

3^2 + 4^2 = 9 + 16 = 25.

Front

What is the base in the expression 5^4?

Back

The base in the expression 5^4 is 5.

Front

Evaluate: 2 x (3 + 5)

Back

2 x (3 + 5) = 2 x 8 = 16.

Front

What is 10^0?

Back

Any non-zero number raised to the power of 0 is 1. Therefore, 10^0 = 1.

Front

Simplify: 6 + 2 x 3

Back

Using the order of operations, 6 + 2 x 3 = 6 + 6 = 12.

Front

What is 4^3?

Back

4^3 = 4 x 4 x 4 = 64.

Front

Calculate: (2 + 3)^2

Back

(2 + 3)^2 = 5^2 = 25.

Front

What is the result of 5 + 3 x 2?

Back

Using the order of operations, 5 + 3 x 2 = 5 + 6 = 11.
