Pedro is given that log50−−√=0.8495. Without using a calculator, how can Pedro find log2√?
A log50−−√=log25−−√×log2√=5×log2√, so dividing 0.8495 by 5 will give the value of log2√.
B log50−−√=log25−−√+log2√=5+log2√, so subtracting 5 from 0.8495 will give the value of log2√.
C log100−−−√=log50−−√+log2√, and log100−−−√=1, so subtracting 0.8495 from 1 will give the value of log2√.
D log100−−−√=log50−−√×log2√, and log100−−−√=1, so dividing 1 by 0.8495 will give the value of log2√.
