Question

When we multiply a decimal number by${10}^{17},$ how many places does a decimal point move to the right?

Answer 1

When multiplying a decimal by a power of ten, move the decimal place to the right as many places as the power of ten has 0s.

The multiplier ${10}^{17}$ has $17$ zeros, so, we move the decimal point $17$ places to the right of a decimal number.
