AnswerWe have, (998) 3 =(1000−2) 3

AnswerWe have, (998) 3 =(1000−2) 3 =(1000)

AnswerWe have, (998) 3 =(1000−2) 3 =(1000) 3

AnswerWe have, (998) 3 =(1000−2) 3 =(1000) 3 +(−2)

AnswerWe have, (998) 3 =(1000−2) 3 =(1000) 3 +(−2) 3

AnswerWe have, (998) 3 =(1000−2) 3 =(1000) 3 +(−2) 3 +3(1000)(−2)(1000−2)

AnswerWe have, (998) 3 =(1000−2) 3 =(1000) 3 +(−2) 3 +3(1000)(−2)(1000−2) =1000000000−8−6000(998)

AnswerWe have, (998) 3 =(1000−2) 3 =(1000) 3 +(−2) 3 +3(1000)(−2)(1000−2) =1000000000−8−6000(998) =1000000000−8−5988000

AnswerWe have, (998) 3 =(1000−2) 3 =(1000) 3 +(−2) 3 +3(1000)(−2)(1000−2) =1000000000−8−6000(998) =1000000000−8−5988000 =994011992
