[tex]2 \sqrt{12} + 3 \sqrt{75} - \sqrt{300} \\ = 2 \sqrt{4 \times 3} + 3 \sqrt{25 \times 3} - \sqrt{100 \times 3} \\ = 2 \times 2 \sqrt{3} + 5 \times 3 \sqrt{3} - 10 \times \sqrt{3} \\ = 4 \sqrt{3} + 15 \sqrt{3} - 10 \sqrt{3} = 9 \sqrt{3} [/tex]
jawaban: D
5.
[tex] {25}^{ \frac{1}{2} } \times {8}^{ \frac{4}{3} } = { ({5}^{2} )}^{ \frac{1}{2} } \times { ({2}^{3} )}^{ \frac{4}{3} } = 5 \times {2}^{4} \\ = 5 \times 16 = 80[/tex]
jawaban: B
