Answer:
Step-by-step explanation:
I take it that this is some sort of ratio. Start by solving the brackets on the left.
Brackets: 1/3 - 1/10
Brackets: 10/30 - 3/30
Brackets: 7/30
Brackets^2: 49/900
Brackets^2 - 1/5: 49/900 - 180/900
Brackets^2 - 1/5: -131/900
(2/5)^2 = 4/25
The way this read, it should be
[tex]\frac{\frac{-131}{900} }{\frac{4}{25} }[/tex]
Which when you invert and multiply becomes
[tex]\frac{-131}{900} * \frac{25}{4}[/tex]
which finally becomes
[tex]\frac{-131}{144}[/tex]
