Question

a-3b/ab-1/b при a=3/17 b=2 корень 51

Answer 1

A = 3/17

B = √51 * 2

(A - 3B) / (AB - 1/B)

= (3/17 - 3 * (√51 * 2)) / ((3/17) * (√51 * 2) - 1 / (√51 * 2))

= (3/17 - 6√51) / ((3/17) * (√51 * 2) - 1 / (√51 * 2))

= (3/17 - 6√51) / ((6√51/17) - (1/2√51))

= (3/17 - 6√51) * (2√51 / (6√51 - 1))

= (3/17 - 6√51) * (2√51 / (6√51 - 1))

= (6√51 - 3/17) * (2√51 / (6√51 - 1))

= (12√51 - 6/17) * (2√51 / (12√51 - 1))

= (24√51 - 12/17) / (24√51 - 2)

Ответ: (24√51 - 12/17) / (24√51 - 2).
