Question

Diketahui log 2 = 0,3010 , log 3 = 0,4771 , log 7 = 0,8451 maka nilai log 882 =

Answer 1

= log 7*7*3*3*2
= 2*log7 + 2*log3 + log2
= 2*0,8451 + 2*0.4771 + 0,3010
= 1,6902 + 0,9542 + 0,3010
=2,9454

Answer 2

Log 882
=log 7²×3²×2
=log 7² + log 3² + log 2
=2 log 7 + 2 log 3 + log 2
=2(0,8451)+2(0,4771)+0,3010
=1,6902+0,9542+0,3010
=2,9454
