Work: Calculate the value of equation 14/9-(9/7-(14/9)^2+1)/((-2*81/196)-2*(14/9)) .
Question type: Mathematical calculation
Solution:
14/9-(9/7-(14/9)^2+1)/((-2*81/196)-2*(14/9))
=14/9-(9/7-1.555556^2+1)/((-2*81/196)-2*(14/9))
=14/9-(-0.13404)/((-2*81/196)-2*(14/9))
=14/9-(-0.13404)/((-0.826531)-2*(14/9))
=14/9-(-0.13404)/(-0.826531-2*1.555556)
=14/9-(-0.13404)/(-3.937643)
=1.555556-(-0.13404)/(-3.937643)
=1.555556-0.034041
=1.521515
Answer:14/9-(9/7-(14/9)^2+1)/((-2*81/196)-2*(14/9))=1.521515
