Question

Ted is asked to multiply 10^2*18.72.how should he move the decimal point to get the correct product?

Answer 1

1. 10^2= 100 (10^2 means 10*10, which equals 100. For example 10^3 means 10*10*10= 1000)
2. 100*18.72=1,872.0 (The decimal needs to be moved 2 times to the right because the number is increasing by 100x).
