How do i simplify 3b x 4c

The given expression is 3b x 4c

In this 3 and 4 are the coefficients and b and c are the variables.

When we multiply the coefficients we get:

3 x 4 = 12

And the product of variables is:

b x c = bc

Now multiply the product of coefficients and product of variables we get:

12 x bc = 12bc

So 12bc is the answer.
