[1/1 Formula]
Work: Calculate the value of equation (0.3*(0.3-0.145)*(0.3-0.145)+0.4*(0.1-0.145)*(0.1-0.145)+0.3*(0.05-0.145)*(0.05-0.145),1/2) .
Question type: Mathematical calculation
Solution:
(0.3*(0.3-0.145)*(0.3-0.145)+0.4*(0.1-0.145)*(0.1-0.145)+0.3*(0.05-0.145)*(0.05-0.145),1/2)
=(0.3*0.155*(0.3-0.145)+0.4*(0.1-0.145)*(0.1-0.145)+0.3*(0.05-0.145)*(0.05-0.145),1/2)
=(0.3*0.155*0.155+0.4*(0.1-0.145)*(0.1-0.145)+0.3*(0.05-0.145)*(0.05-0.145),1/2)
=(0.3*0.155*0.155+0.4*(-0.045)*(0.1-0.145)+0.3*(0.05-0.145)*(0.05-0.145),1/2)
=(0.3*0.155*0.155+0.4*(-0.045)*(-0.045)+0.3*(0.05-0.145)*(0.05-0.145),1/2)
=(0.3*0.155*0.155+0.4*(-0.045)*(-0.045)+0.3*(-0.095)*(0.05-0.145),1/2)
=(0.3*0.155*0.155+0.4*(-0.045)*(-0.045)+0.3*(-0.095)*(-0.095),1/2)
=0.010725
=0.005363
Answer:(0.3*(0.3-0.145)*(0.3-0.145)+0.4*(0.1-0.145)*(0.1-0.145)+0.3*(0.05-0.145)*(0.05-0.145),1/2)=0.005363
