Which alternative format is equivalent to 7.4 x 10^8 Hz?

To determine the equivalent format to 7.4 x 10^8 Hz, it's essential to convert the scientific notation into hertz (Hz) and then into other frequency units.

The notation 7.4 x 10^8 Hz represents a frequency in hertz, where 1 Hz is one cycle per second. In terms of converting this into kilohertz (kHz) or megahertz (MHz):

• 1 kHz is equal to 10^3 Hz (or 1000 Hz).
• 1 MHz is equal to 10^6 Hz (or 1,000,000 Hz).

So to convert the given frequency:

• To convert from Hz to MHz, divide by 10^6:
  7.4 x 10^8 Hz / 10^6 = 7.4 x 10^2 MHz = 740 MHz.

This conversion directly leads to 740 MHz being equivalent to 7.4 x 10^8 Hz, confirming that the correct answer is indeed 740 MHz.

Frequencies expressed in kHz and MHz relate to one another in powers of ten, and understanding these conversions is crucial for interpreting and working with electronic and communication
