Answer:
Explanation:
The value of the frequency is not given. Lets assume it to be 14603 kHz. the question now becomes:
A radio technician measures the frequency of an AM radio transmitter. The frequency is 14603 kHz . What is the frequency in megahertz?
Answer:
kilo to mega = 10^-3
then
14603 kHz = 14603 *10^-3 MHz = 14.603 MHz
