Sagot :

To solve this problem, we need to find the product of the first three prime numbers.

Prime numbers are numbers greater than 1 that have no positive divisors other than 1 and themselves. The first three prime numbers are:

1. 2
2. 3
3. 5

To find the product, we multiply these three prime numbers together:

[tex]\[ 2 \times 3 \times 5 \][/tex]

First, multiply the first two numbers:

[tex]\[ 2 \times 3 = 6 \][/tex]

Next, multiply the result by the third number:

[tex]\[ 6 \times 5 = 30 \][/tex]

Thus, the product of the first three prime numbers is 30.

So, the correct answer is:
a. 30
