If the operation * is defined as a * b = 3a + b, find the value of 3 * 5.
see previous post, same type of question.

To find the value of 3 * 5, we substitute the values of a and b in the given operation * with the given numbers.
In this case, a = 3 and b = 5.
So, 3 * 5 = 3(3) + 5.
Now, we can simplify this expression by performing the multiplication and addition:
3 * 5 = 9 + 5.
Finally, we can add the numbers together:
3 * 5 = 14.
Therefore, the value of 3 * 5 is 14.
