Work: Calculate the value of equation ((4.78+1.3)×2×0.5+(5.88+2)×2×0.5+(6.98+2.8)×2×0.5)×1+((5.08+1.3)×2×0.5+(6.18+2)×2×0.5+(7.28+2.8)×2×0.5)×1 .
Question type: Mathematical calculation
Solution:
((4.78+1.3)×2×0.5+(5.88+2)×2×0.5+(6.98+2.8)×2×0.5)×1+((5.08+1.3)×2×0.5+(6.18+2)×2×0.5+(7.28+2.8)×2×0.5)×1
=(6.08×2×0.5+(5.88+2)×2×0.5+(6.98+2.8)×2×0.5)×1+((5.08+1.3)×2×0.5+(6.18+2)×2×0.5+(7.28+2.8)×2×0.5)×1
=(6.08×2×0.5+7.88×2×0.5+(6.98+2.8)×2×0.5)×1+((5.08+1.3)×2×0.5+(6.18+2)×2×0.5+(7.28+2.8)×2×0.5)×1
=(6.08×2×0.5+7.88×2×0.5+9.78×2×0.5)×1+((5.08+1.3)×2×0.5+(6.18+2)×2×0.5+(7.28+2.8)×2×0.5)×1
=23.74×1+((5.08+1.3)×2×0.5+(6.18+2)×2×0.5+(7.28+2.8)×2×0.5)×1
=23.74×1+(6.38×2×0.5+(6.18+2)×2×0.5+(7.28+2.8)×2×0.5)×1
=23.74×1+(6.38×2×0.5+8.18×2×0.5+(7.28+2.8)×2×0.5)×1
=23.74×1+(6.38×2×0.5+8.18×2×0.5+10.08×2×0.5)×1
=23.74×1+24.64×1
=23.74+24.64×1
=23.74+24.64
=48.38
Answer:((4.78+1.3)×2×0.5+(5.88+2)×2×0.5+(6.98+2.8)×2×0.5)×1+((5.08+1.3)×2×0.5+(6.18+2)×2×0.5+(7.28+2.8)×2×0.5)×1=48.38
