Question

Jika log 5= 0,6990 dan log 7= 0,8451 maka nilai log √175 adalah

Answer 1

Log √175 = log 175^1/2
= (log 35 . 7 )^1/2
= log 35^1/2 + log 7^1/2
log 5^1/2 + log 7 ^1/2 + log 7 ^1/2
( 0,6990 + 0,8451 +0,8451)^1/2
2,3892^1/2
√2,3892
1,5457

Answer 2

Log akar 175= log (5^2.7)^1/2
1/2.[log(5^2.7)
1/2 log 5^2+1/2 log 7
log 5+1/2 log 7
0,6990+0,42255
1,12155
