Work: Calculate the value of equation (lg2)^2+lg2*lg50+lg25 .
Question type: Mathematical calculation
Solution:
(lg2)^2+lg2*lg50+lg25
=0.30103^2+lg2*lg50+lg25
=0.301030^2+0.30103*lg50+lg25
=0.301030^2+0.30103*1.69897+lg25
=0.301030^2+0.30103*1.69897+1.39794
=0.0906190609+0.30103*1.69897+1.39794
=0.0906190609+0.511441+1.39794
=0.60206+1.39794
=2
Answer:(lg2)^2+lg2*lg50+lg25=2
