Work: Calculate the value of equation 2*lg5-1+3^log(3,7)+lg4 .
Question type: Mathematical calculation
Solution:
2*lg5-1+3^log(3,7)+lg4
=2*lg5-1+3^1.771244+lg4
=2*0.69897-1+3^1.771244+lg4
=2*0.69897-1+3^1.771244+0.60206
=2*0.69897-1+7.000001929020674+0.60206
=1.39794-1+7.000001929020674+0.60206
=0.39794+7.000001929020674+0.60206
=7.397942+0.60206
=8.000002
Answer:2*lg5-1+3^log(3,7)+lg4=8.000002
