$\dfrac{3}{5}$ + $\dfrac{12}{45}$ x $\dfrac{2^5}{10-(-5)}$ - $\dfrac{3}{7}$ - ($\dfrac{57}{4}$ : $\dfrac{1}{2}$ ) x 4²
= $\dfrac{3}{5}$ + $\dfrac{12}{45}$ x $\dfrac{32}{15}$ - $\dfrac{3}{7}$ - ($\dfrac{57}{4}$ : $\dfrac{1}{2}$) x 16
= $\dfrac{3}{5}$ + $\dfrac{12}{45}$ x $\dfrac{32}{15}$ - $\dfrac{3}{7}$ - $\dfrac{57}{2}$ x 16
= $\dfrac{3}{5}$ + $\dfrac{128}{225}$ - $\dfrac{3}{7}$ - 456
= $\dfrac{135}{225}$+ $\dfrac{128}{225}$ - $\dfrac{3}{7}$ - 456
= $\dfrac{263}{225}$ - $\dfrac{3}{7}$ - 456
= $\dfrac{1841}{1575}$ - $\dfrac{675}{1575}$ - 456
= $\dfrac{1166}{1575}$ - 456
= $\dfrac{1166}{1575}$ - $\dfrac{718200}{1575}$
= -455,2596
