Question

Помогите пожалуйста решить

Answer 1

Ответ:

3 * (5 - (5)^(1/2))

Пошаговое объяснение:

((17*(6/7))^(1/2) - (6*(3/7))^(1/2)) / (5/63)^(1/2)

(((17*7+6)/7)^(1/2) - ((6*7+3)/7)^(1/2)) * (63/5)^(1/2)

((125/7)^(1/2) - (45/7)^(1/2)) * (63/5)^(1/2)

(125/7)^(1/2) * (63/5)^(1/2) - (45/7)^(1/2) * (63/5)^(1/2)

(125/7 * 63/5)^(1/2) - (45/7 * 63/5)^(1/2)

(125/5 * 63/7)^(1/2) - (45/5 * 63/7)^(1/2)

(25*9)^(1/2) - (5*9)^(1/2)

5*3 - 3*(5)^(1/2) = 3 * (5 - (5)^(1/2))

вроде так
