what happen to the 7 and the log?

OpenStudy (anonymous):

CM ignored it.

OpenStudy (anonymous):

A noble strategy.

OpenStudy (anonymous):

are you suppose to ignore it?

OpenStudy (anonymous):

so the whole thing should be 7^2(log(2)(16)) or "seven to the power of all of two multiplied by log base two, sixteen close bracket" or 7^(2*4) or 7^8 or 5764801

OpenStudy (anonymous):

no you aren't supposed to ignore it. it was just a mistake.

OpenStudy (anonymous):

ok
