Question 876530
Please help me solve this equation:
1.-  {{{log(8, (1024))=x+3 }}} 
8^(x+3)=1024
(x+3)log(8)=log(1024)
x+3=log(1024)/log(8)
x=log(1024)/log(8)-3=0.3333…
...
2.- {{{log(x, (8))=3}}}
x^3=8=2^3
x=2
..
3.- {{{log(5,(.15 * 10^2))=x}}}
 {{{log(5,(15))=x}}}
5^x=15
x log5=log15
x=log15/log5=1.68
