Let f(x) =x+1/2x +1/2x+1/2x+....... Compute the value of f(100).f(100). Share with your friends Share 0 Anuradha Sharma answered this Although your question is not clear as it is not clear whether x is in denominator or it is in the numerator so assuming it is in the denominator we can say, fx=x+12x+ 12x+12x+12x+......So f100=100+1200+1200+1200+.....=∞This is a infinite series and sum of this series will be infinite as for a GP with r = 1we get sum as infinityNow f100.f100=∞×∞=∞So we request you to kindly recheck your question. -2 View Full Answer
