If the integers a , b are coprime , then does it follow that for any positive integers $ a ^ l $ and $ b ^ m $ are coprime as well ?
If the integers a , b are coprime , then does it follow that for any positive integers , -LSB- math -RSB- a ^ l -LSB- / math -RSB- and -LSB- math -RSB- b ^ m -LSB- / math -RSB- are coprime as well ?
