Question

Find the value of x 3/4 4 =81/x

Answer 1

I’d say that the expression in the question, x4−81x+3 is already “simplified”.

But I assume that is not the intended expression. When writing mathematical expressions, precision matters. Use math mode. If you don’t know how to use math mode, have a look here: . If you can’t be bothered, at least use parentheses.

I assume you meant x4−81x+3 . This indeed can be simplified, with one very import caveat.

If we are told that x≠3 , we can simplify this to (x2+9)(x−3) . You can expand this if you like — the term “simplify” is not unambiguous.
