Question

comparati numerele a si b stiind ca a=(4,3x0,2+0,196 :1,4):10² si b=(2,88:2,4+0,7³–1,3) :1,3

Answer 1

a=(4,3x0,2+0,196 :1,4):10² = (43/10*2/10+196/1000:14/10):100=
=(86/100+14/10):100=(86+140)/100*1:100=226/100:100=226/10000=0,0226


si b=(2,88:2,4+0,7³–1,3) :1,3 = 288/100*10/24+ 343/1000-13/10):13/10 =12/10+343/100-13/10):13/10= 243/1000*10/13= 243/1300=0,186923077

b este mai mare decât a
