+318 Write the expression in expanded form. do not simplify.
ln[x(SQ RT X-1)/X^4+4]
i got the answer 2ln(x)+ln(x-1)-2ln(x^4+4)/2
and it is saying its the correct answer but not in correct form. PLEASE HELP
+129852 Ln [ x * √ [ x - 1 ] / (x^4 + 4 ] =
Ln (x) + Ln (√[x + 1] ) - Ln ( x^4 + 4 ]) =
Ln (x ) + (1/2)Ln (x - 1) - Ln (x^4 + 4) =
[ 2Ln (x) + Ln ( x - 1) - 2Ln (x^4 + 4) ] / 2
You just needed to bracket the numerator...the way you wrote it looks like you are just dividing the last term by 2, instead of all three terms.....brackets and parentheses are important.....
