Work: Calculate the value of equation (23÷54-7÷2×7÷9+2)^2+(2×sqrt(2)×23÷54-sqrt(2)×7÷9)^2+(2×7÷9-2)^2 .
Question type: Mathematical calculation
Solution:
(23÷54-7÷2×7÷9+2)^2+(2×sqrt(2)×23÷54-sqrt(2)×7÷9)^2+(2×7÷9-2)^2
=-0.296296^2+(2×sqrt(2)×23÷54-sqrt(2)×7÷9)^2+(2×7÷9-2)^2
=-0.296296^2+(2×sqrt2×23÷54-sqrt(2)×7÷9)^2+(2×7÷9-2)^2
=-0.296296^2+(2×sqrt2×23÷54-sqrt2×7÷9)^2+(2×7÷9-2)^2
=-0.296296^2+0.104757^2+(2×7÷9-2)^2
=-0.296296^2+0.104757^2+(-0.444444)^2
=0.087791319616+0.104757^2+(-0.444444)^2
=0.087791319616+0.010974029049+(-0.444444)^2
=0.087791319616+0.010974029049+0.197530469136
=0.098765+0.197530469136
=0.296295
Answer:(23÷54-7÷2×7÷9+2)^2+(2×sqrt(2)×23÷54-sqrt(2)×7÷9)^2+(2×7÷9-2)^2=0.296295
