16x^4-81y^4 difference of perfect squares...

(4x^2-9y^2)(4x^2+9y^2) that's one of the equivalents...

(2x+3y)(2x-3y)(4x^2+9y^2) that's another one of them...

Greetings!

Convert both terms into improper fractions:
$=9/1-59/8$
Find the LCM.
$=72/8-59/8$
Simplify.
$=13/8$
Convert to Mixed Number.
$=1 \frac{5}{8}$

The second answer would be correct.

Hope this helps.
