Ответ: 8(ост.2)
Ну а фото или сам пример?
А). √2 * (√64\√8) = √2 * √(64\8) = √2 * √8 = √2 * √(4*2) = √2 * 2√2 = 2(√2*<span>√2)=2*2=4
</span>б1).√3\4 * √9\16 = (3<span>√3) \ 64</span>
б2). √3\4 * √9\16 = √(3\16) * √(9\256) = √ ((3\16)*(9\256)) = √(27\4096) = √27\√4096 = √27\64 = √(3*9) \ 64 = (3√3)\64
