[1/1 Formula]
Work: Calculate the value of equation 3/2*(52-39)*(51-39)+19*18+1/2*(39-18)*(39-18-1) .
Question type: Mathematical calculation
Solution:
3/2*(52-39)*(51-39)+19*18+1/2*(39-18)*(39-18-1)
=3/2*13*(51-39)+19*18+1/2*(39-18)*(39-18-1)
=3/2*13*12+19*18+1/2*(39-18)*(39-18-1)
=3/2*13*12+19*18+1/2*21*(39-18-1)
=3/2*13*12+19*18+1/2*21*20
=1.5*13*12+19*18+1/2*21*20
=19.5*12+19*18+1/2*21*20
=234+19*18+1/2*21*20
=234+342+1/2*21*20
=234+342+0.5*21*20
=234+342+10.5*20
=234+342+210
=576+210
=786
Answer:3/2*(52-39)*(51-39)+19*18+1/2*(39-18)*(39-18-1)=786
