Bentuk sederhana dari 5sqrt(243)+2sqrt(27)-sqrt(75)-3sqrt(48) adalah ...

$$5\sqrt{243} = 5\sqrt{81 \times 3} = 5 \times 9\sqrt{3} = 45\sqrt{3}$$ $$2\sqrt{27} = 2\sqrt{9 \times 3} = 2 \times 3\sqrt{3} = 6\sqrt{3}$$ $$\sqrt{75} = \sqrt{25 \times 3} = 5\sqrt{3}$$ $$3\sqrt{48} = 3\sqrt{16 \times 3} = 3 \times 4\sqrt{3} = 12\sqrt{3}$$

$$(45 + 6 - 5 - 12)\sqrt{3}$$ $$(51 - 5 - 12)\sqrt{3}$$ $$(46 - 12)\sqrt{3}$$ $$34\sqrt{3}$$

The simplified form is $34\sqrt{3}$. Comparing this with the given options, it matches option A.

The final answer is $\text{A. } 34\sqrt{3}$.
