1.sederhanakan bentuk pangkat a.(2³)²-(-2)^6 b.5^5×5³/5² 2.hasil dari a.√72+√98+√147-√27 b.√12×√27 c.√256+√196 3.hasil dari 2(√2+1) (2-3) tolong dibantu ya kk p

a)
[tex] {2}^{6} - ( - 2 {}^{6} ) = 0 \\ \frac{ {5}^{5}. {5}^{3} }{ {5}^{2} } = \frac{5 {}^{8} }{ {5}^{2} } = {5}^{6} \\ [/tex]
2)
[tex] \sqrt{4 \times 9\times 2 } + \sqrt{49 \times2 } + \sqrt{ 3\times 49} - \sqrt{ 9\times3} \\ 6 \sqrt{2} + 7 \sqrt{2} + 7 \sqrt{3} - 3 \sqrt{3} \\ = 13 \sqrt{2} - 4 \sqrt{3} [/tex]
b)
[tex] \sqrt{4 \times 3} \times \sqrt{9 \times 3} \\ 2 \sqrt{3} \times 3 \sqrt{3} \\ 6 \times 3 \\ = 18[/tex]
c)
[tex] \sqrt{256} + \sqrt{196} \\ = \sqrt{4\times 64} + \sqrt{4\times 49} \\ (2 \times 8 )+( 2 \times 7) \\ = 16 + 14 = 30[/tex]

[tex](2 \sqrt{2 } + 2)( - 1) = - 2 \sqrt{ 2 } - 2[/tex]
