Answer:
<u><em>41 is a prime number</em></u>
<u><em></em></u>
Step-by-step explanation:
A prime number is <em>a number that will never be the product of two numbers</em>.
To find the prime number, you can ask yourself if each number is the product of two other numbers.
18: 18 is the product of <u>6 x 3</u>, or <u>2 x 9</u>. 18 is <em>not</em> a prime number.
41: 41 is not the product of any two numbers. This means 41 <em>is</em> a prime number.
45: 45 is the product of <u><em>9 x 5</em></u>. 45 is <em>not</em> a prime number.
77: 77 is the product of <u>7 x 11</u>. 77 is <em>not</em> a prime number.
93: 93 is the product of <u>31 x 3</u>. 93 is <em>not</em> a prime number.
