30, 30, 32, 32, 34, 38, 38, 38. Thats how you first need to set it up then what you do is add them all up which would equal to 272. Then you take 272 dived by how many numbers there are (theres 8 numbers) so you do 272/8 which would be 34! So 34 would be your answer.

Log1/2 28? What is it?

I am Lyosha [343]

$\log_a(b\cdot c)=\log_ab+\log_ac\\\\\log_ab^c=c\cdot\log_ab\\\\\log_aa=1\\--------------------\\\log_\frac{1}{2}28=\log_\frac{1}{2}(4\cdot7)=\log_\frac{1}{2}4+\log_\frac{1}{2}7=\log_\frac{1}{2}2^2+\log_\frac{1}{2}7\\\\=2\log_\frac{1}{2}2+\log_\frac{1}{2}7=\boxed{2+\log_\frac{1}{2}7}$

$\log_ab=\frac{\log_cb}{\log_ca}\\-------------------------\\\log_\frac{1}{2}7=\frac{\log\frac{1}{2}}{\log7}\approx\frac{-0.6931}{1.9459}\approx-0.3562\\\\therefore\\\\\boxed{\log_\frac{1}{2}28\approx2+(-0.3562)=1.6438}$
