You can put this solution on YOUR website!
2^-5 = (1 + 0.23x)^-3, (working eqn)
\n" ); document.write( "Multiply both eqns by $\"-1%2F3\"$ to isolate variable with $\"x\"$ :
\n" ); document.write( " $\"%282%5E-5%29%5E%28-1%2F3%29=%28%281%2B0.23x%29%5E-3%29%5E%28-1%2F3%29\"$
\n" ); document.write( " $\"2%5E%285%2F3%29=%281%2B0.23x%29%5Ecross%28-3%29%5E%28-1%2Fcross%283%29%29\"$
\n" ); document.write( " $\"3.1748=1%2B0.23x\"$
\n" ); document.write( " $\"3.1748-1=0.23x\"$
\n" ); document.write( " $\"2.1748%2F0.23=cross%280.23%29x%2Fcross%280.23%29\"$
\n" ); document.write( " $\"x=9.45565\"$ , ANSWER
\n" ); document.write( "check by going back working eqn:
