for questions 9 and 10, use $a = 5$ and $b = 2$.

1. $ab =$
2. $ba =$

Explanation:

Question 1

Step1: Recall exponent definition

$3^2$ means 3 multiplied by itself 2 times, so $3\times3$.

Step2: Calculate the product

$3\times3 = 9$.

Step1: Recall division of integers

$\frac{18}{3}$ is the number of times 3 fits into 18.

Step2: Perform the division

18 divided by 3 equals 6.

Step1: Recall exponent notation

$5^3$ means 5 multiplied by itself 3 times, i.e., $5\times5\times5$ (or $5\bullet5\bullet5$).

Step2: Analyze options

• Option a: $5\times3 = 15$, not equal to $5^3$.
• Option b: $3\bullet3\bullet3\bullet3\bullet3=3^5$, not equal to $5^3$.
• Option c: $3\times5 = 15$, not equal to $5^3$.
• Option d: $5\bullet5\bullet5$ is $5^3$.

Answer:

9
