1。The answer is 4401000。。。000- 74-------------999。。。926So it's 9*48+2+6=432+8=4402。It could also be written as (√(2x)-√x)/x。3。The answer is D。"prime-saturated" is (product of all different prime factor) < √xA。99=3*3*11,33>10,not fitB。98=2*7*7,14>10,not fitC。97 is prime number,definitly not fitD。96=3*2*2*2*2*2,610,not fit
