3. kellikelz Group Title

4. kellikelz Group Title

where do the parenthesis go

5. MATTW20 Group Title

Idk wherever you need to show that there is a break in the fractions for example your question might be (x^4/4lnx)-(x^4)/16 or x^4/(4lnx-x^4/16) etc. it's hard to tell where one fraction ends and another begins you know?

6. kellikelz Group Title

7. kellikelz Group Title

$(x^4/4)\ln x-(x^4/16)$
