[1/1 Formula]
Work: Calculate the value of equation (4/7)^2*0.15^2+(3/7)^2*0.04 .
Question type: Mathematical calculation
Solution:
(4/7)^2*0.15^2+(3/7)^2*0.04
=0.571429^2*0.15^2+(3/7)^2*0.04
=0.571429^2*0.15^2+0.428571^2*0.04
=0.326531102041*0.15^2+0.428571^2*0.04
=0.326531102041*0.0225+0.428571^2*0.04
=0.326531102041*0.0225+0.183673102041*0.04
=0.007347+0.183673102041*0.04
=0.007347+0.007347
=0.014694
Answer:(4/7)^2*0.15^2+(3/7)^2*0.04=0.014694
