Question

1. when a number is multiplied by $10^3$, how many places does the decimal point move to the right?

a 0
b 1
c 3
d 10

Explanation:

Step1: Recall the rule of decimal movement

When multiplying a number by \(10^n\) (where \(n\) is a positive integer), the decimal point moves \(n\) places to the right.

Step2: Identify the exponent

In the problem, we are multiplying by \(10^3\), so \(n = 3\). This means the decimal point moves 3 places to the right.

Answer:

C. 3
