198 = (200 - 2) so use 6*200 - 6*2
If x is used to represent the unknown number, then the expression for 20 times a number would be 20x.

3x^6
You use the distributive property every time you use the standard multiplication method, whether mentally or with pencil and paper. In this case, 6 x 53 = 6 x (50 + 3) = 6 x 50 + 6 x 3.

It can be known as: Multiply, Divide, Add, and Subtract...and more.
Most people who multiply mentally are using some form of the distributive property. If you wanted to do something like 47 x 5 in your head, that's (40 x 5) + (7 x 5) = 200 + 35 = 235

The exponent.
An exponential expression is a problem with no answer usually used to answer a question such as, Find the Value ; 2 as a base and 5 as an exponent.; The answer would be 32 because to find the value of an exponent you multiply the number in the base by itself as many times that it says in the exponent.Ex: 2*2*2*2*2=32
8x^4
The exponent shows how many times the base is used as a factor.
