Question 968341

Please help me solve this equation:  4^(x+1)-7=14
<pre>{{{4^(x + 1) - 7 = 14}}}
{{{4^(x + 1) = 14 + 7}}}
{{{4^(x + 1) = 21}}} -------- Exponential form
{{{log (4, 21) = x + 1}}} ------ Logarithmic form
{{{x + 1 = log(21)/log(4)}}} ------- Applying change of base
{{{highlight_green(x = log(21)/log(4) - 1)}}}, or {{{highlight_green(x = 1.196158711)}}}
