To calculate 3 x 100, we can utilize the rule for multiplying by powers of 10, which states that multiplying a number by 10, 100, 1000, etc., effectively shifts the decimal point of that number to the right. In this case, 100 is the same as 10 raised to the power of 2 (102).
So, when we multiply 3 by 100, we can think of it as:
3 x 100 = 3 x 102
This means we take the number 3 and shift its decimal point two places to the right. Starting with 3.0, when we shift the decimal two places to the right, we get:
- First shift: 30.0
- Second shift: 300.0
Thus, 3 x 100 equals 300. In conclusion, the answer is:
3 x 100 = 300
