Question

Simplify 5a x 2c x 3d

Answer 1

5a* 2c* 3d
= (5* 2* 3)* (a* c* d) 
= 30* (a* c* d)
= 30acd

The final answer is 30acd.

Answer 2

The goal in simplifying numbers is to reduce it that can be best seen in the eye. In here, you are given 5a x 2c x 3d. Note that 5, 2 and 3 are coefficients and a, c and d, are variables. Multiply first the coefficients 5, 2 and 3 and you get 30. Always remember that in multiplying numbers, especially variables, the base of the exponent must be equal. However, you have variables of a, c and, d. You cannot multiply or add them because they are different. So the answer is 30acd.
