Work: Calculate the value of equation 2/3*(3+√17)^2/4+2*(3+√17)-1/3*(3+√17)^3/8 .
Question type: Mathematical calculation
Solution:
2/3*(3+√17)^2/4+2*(3+√17)-1/3*(3+√17)^3/8
=2/3*7.123106^2/4+2*(3+√17)-1/3*(3+√17)^3/8
=2/3*7.123106^2/4+2*7.123106-1/3*(3+√17)^3/8
=2/3*7.123106^2/4+2*7.123106-1/3*7.123106^3/8
=2/3*50.738639087236002/4+2*7.123106-1/3*7.123106^3/8
=2/3*50.738639087236002/4+2*7.123106-1/3*361.416704514125286/8
=0.666667*50.738639087236002/4+2*7.123106-1/3*361.416704514125286/8
=33.825776/4+2*7.123106-1/3*361.416704514125286/8
=8.456444+2*7.123106-1/3*361.416704514125286/8
=8.456444+14.246212-1/3*361.416704514125286/8
=8.456444+14.246212-0.333333*361.416704514125286/8
=8.456444+14.246212-120.472114/8
=8.456444+14.246212-15.059014
=22.702656-15.059014
=7.643642
Answer:2/3*(3+√17)^2/4+2*(3+√17)-1/3*(3+√17)^3/8=7.643642
