Please solve for x;
\n" ); document.write( "assume you mean
\n" ); document.write( "(a) $\"log%28x%2C+%28121%29%29+=+2\"$
\n" ); document.write( "put it in the exponent form
\n" ); document.write( " $\"x%5E2+=+121\"$
\n" ); document.write( " $\"x+=+sqrt%28121%29\"$
\n" ); document.write( "x = 11
\n" ); document.write( ":
\n" ); document.write( "(b) $\"log%284%2C+%281%2F256%29%29+=+x\"$
\n" ); document.write( "the exponent form
\n" ); document.write( " $\"4%5Ex+=+%281%2F256%29\"$
\n" ); document.write( "we know that 4*4*4*4 = 256 and that negative exponent gives the reciprocal
\n" ); document.write( " $\"4%5E-4+=+1%2F256\"$
\n" ); document.write( "x = -4
\n" ); document.write( ":
\n" ); document.write( "(c) $\"log%281%2F3%2C+%28x%29%29+=+5\"$
\n" ); document.write( "exponent equiv
\n" ); document.write( " $\"%281%2F3%29%5E5+=+x\"$
\n" ); document.write( "x = $\"%281%2F3%29%2A%281%2F3%29%2A%281%2F3%29%2A%281%2F3%29%2A%281%2F3%29\"$
