i am having problems with this problem
Time standards are now based on atomic clocks. A promising second standard is based on pulsars, which are rotating neutron stars (highly compact stars consisting only of neutrons). Some rotate at a rate that is highly stable, sending out a radio beacon that sweeps briefly across Earth once with each rotation, like a lighthouse beacon. Suppose a pulsar rotates once every 1.572 806 448 872 75 +/-5 ms, where the trailing +/-5 indicates the uncertainty in the last decimal place (it does not mean +/-5 ms).
(b) How much time does the pulsar take to rotate 1.0 * 10^6 times? (Give your answer to at least 4 decimal places.)
i converted 1.0e6 to ms by multiplying it to the 1.572 806 448 872 75 and then multiplied it to seconds (thats what they want the answer in), but i keep getting the wrong answer. is it because i didn't consider the +/-5. if so how would i do it
