Пусть V-корень 1) 2/(V11 - V10) + 4/(V11 + V10) = 2(V11 + V10)/(V11 - V10)(V11 + V10) + + 4(V11 - V10)/(V11 + V10)(V11 - V10) = (2V11 + 2V10)/(11-10) + + (4V11 - 4V10)/(11-10) = 2V11 + 2 V10 + 4V11 - 4V10 = 6V11 - 2V10 2) 5/(V6 -V5) - 3/(V6 + V5) = 5(V6 + V5)/V6 - V5)(V6 + V5) - - 3(V6 - V5)/(V6 + V5)(V6 - V5) = (5V6 + 5V5)/(6-5) - - (3V6 - 3V5)/(6-5) = 5V6 + 5V5 - (3V6 - 3V5) = 5V6 + 5V5 - 3V6 + 3V5 = 2V6 + 8V5
