Answer:
2
Step-by-step explanation:
log(21)+log(4)+2(log(5))−log(3)−log(7)
=1.322219+log(4)+2(log(5))−log(3)−log(7)
=1.322219+0.60206+2(log(5))−log(3)−log(7)
=1.924279+2(log(5))−log(3)−log(7)
=1.924279+(2)(0.69897)−log(3)−log(7)
=1.924279+1.39794−log(3)−log(7)
=3.322219−log(3)−log(7)
=3.322219−0.477121−log(7)
=2.845098−log(7)
=2.845098−0.845098
=2
