Log2等于几?

log(2) = 0.30102999566398

2 本题的意思是 2的多少次方等于4 那答案就是2咯

f(8)=f(√2^6)=log(2)√2=1/2 log(√2-1)(3+2√2)=log(√2-1)(√2+1)^2 =-2 (√2+1=1/(√2-1))

等于2倍log2呗~

log1=0 log2=0.3010 log3=0.4771 log4=2*log2 log5=0.6990 log6=0.7782 log7=0.8451 log8=3*log2 log9=2*log3

见图

=log2(4)+log2(5)=2+log2(5)大约等于4.322

log2(1/2)=log2(2^-1)=-1log2(2)=-1 希望对你有帮助

log2 1等于0
