3√40m³-2√90m³-5m√250m serta caranya ya pliss jwb besok dikumpulin

[tex]3 \sqrt{40 {m}^{3} } - 2 \sqrt{90 {m}^{3} } - 5m \sqrt{250m} \\ = 3 \sqrt{4 \times 10} - 2 \sqrt{9 \times 10} - 5 \sqrt{25 \times 10} \\ = 3 \times 2 \sqrt{10} - 2 \times 3 \sqrt{10} - 5 \times 5 \sqrt{10} \\ = 6\sqrt{10} - 6 \sqrt{10} - 5 \sqrt{10} \\ = - 5 \sqrt{10} [/tex]
