Вычислить: 1)√8×50 2)√32×50 3)√108×27(действия все под корнем)...

VekaSolnce $\sqrt{8*50} = \sqrt{8*25*2} = \sqrt{16*25} = \sqrt{16} * \sqrt{25}=4*5=20;$
$\sqrt{32*50} = \sqrt{32*25*2} = \sqrt{64*25} = \sqrt{64} * \sqrt{25} =8*5=40;$
$\sqrt{108*27} = \sqrt{36*3*27} = \sqrt{36*81} = \sqrt{36} * \sqrt{81} = 6*9=54.$

NadDer √(8*50) = √400 = 20
√(32*50 = √1600 = 40
