If log7=0.845, find log(7^200)

OpenStudy (loser66):

log a^b = b*loga

OpenStudy (cwrw238):

so log(7^200) = ?

OpenStudy (anonymous):

yes @cwrw238

OpenStudy (anonymous):

Following what @Loser66 said: You can rewrite log(7^200) as 200*log7, and you already know what log7 is, so.................

OpenStudy (anonymous):

so 200*.845?

OpenStudy (anonymous):

Yep! :D

OpenStudy (anonymous):
