To multiply terms with exponents, the base of both exponents must be the same. In this case they are so multiply the coefficients and add the exponents:

3b⁵ x 9b⁶
(3 x 9)b^{(5 + 6)}
27b¹¹

Christine scored 82% on the test meaning she earned 82% of the possible points on the test. There were 150 possible points on the test so she earned 150 x 0.82 = 123 points. Each question is worth 3 points so she got \( \frac{123}{3} \) = 41 questions right.

To add or subtract terms with exponents, both the base and the exponent must be the same. In this case they are so add the coefficients and retain the base and exponent:

-5b⁴ + 6b⁴
(-5 + 6)b⁴
b⁴

A prime number is an integer greater than 1 that has no factors other than 1 and itself. Examples of prime numbers include 2, 3, 5, 7, and 11.

The least common multiple (LCM) is the smallest positive integer that is a multiple of two or more integers.
