In the expression <span>2a x 3b x 4c,
2, 3 and 4 are the coefficients and a, b and c are the variables.
When such a multiplications is given, multiply the coefficients together and the variables together.
So the product of coefficients = 2</span>×3×4 = 24
the product of variables = a×b×c = abc
Finally multiply the product of coefficients and product of variables.
Final product = 24×abc = 24abc
So <u>24abc</u> is the answer.
