Work: Calculate the value of equation 0.42×3^(-9/8)-18.71×3^(-7/12) .
Question type: Mathematical calculation
Solution:
0.42×3^(-9/8)-18.71×3^(-7/12)
=0.42×3^(-1.125)-18.71×3^(-7/12)
=0.42×3^-1.125-18.71×3^(-0.583333)
=0.42×0.290561847623912-18.71×3^(-0.583333)
=0.42×0.290561847623912-18.71×0.526840832231712
=0.122036-18.71×0.526840832231712
=0.122036-9.857192
=-9.735156
Answer:0.42×3^(-9/8)-18.71×3^(-7/12)=-9.735156
