Question 315262
1. log (base 7) 1/49
{{{ log(7,1/49) }}}
{{{ log(7,1)- log(7,49) }}}
{{{ log(7,7^0)- log(7,7^7) }}}
{{{ 0-7 }}}
{{{ -7 }}}
 
write the expression as a single logarithm 
2. 5log (base b)q+3 log(base b)w 
{{{5log(b,q+3)log(b,w)}}}
{{{log(b,(q+3)^5)log(b,w)}}}
{{{log(b,(q+3)^5+w)}}}
3. 4 log x-6 log (x+2)
{{{4 log(x) - 6log(x+2)}}}
{{{log(x^4) - log((x+2)^6)}}}
{{{log (x^4/(x+2)^6)}}}

4. solve 4^2x=111
{{{4^(2x)=111}}}
{{{log(4,4^(2x))= log(4,111)}}}
{{{2x= log(4,111)}}}
{{{x= log(4,111)/2}}}
{{{x= log(111)/2log(4)}}}
{{{x= 1.7}}}
