To find the value of the expression 42x 100 when x = 2, we first need to substitute the value of x into the expression.
We start with the expression:
42x 100
Substituting x = 2 into the expression gives:
42(2) 100
Next, we perform the multiplication:
42 * 2 = 84
Now we incorporate the 100:
84 * 100 = 8400
Therefore, the value of the expression 42x 100 when x = 2 is 8400.
