Answer 1

Ответ:

Объяснение:

3. b=2015; p=1/6

(b²+36p²)/(b-6p) +(12bp)/(6p-b)=(b²+36p²)/(b-6p)  -(12bp)/(b-6p)=(b²-12bp+(6p)²)/(b-6p)=(b-6p)²/(b-6p)=b-6p=2015 -6·1/6=2015-1=2014

4. (9a+1,5m)/(9a²-1,5am) -(9a-1,5m)/(9a²+1,5am) +(36a)/(9a²-0,25m²)=24/(6a-m)

(3(3a+0,5m))/(3a(3a-0,5m)) -(3(3a-0,5m))/(3a(3a+0,5m)) +(36a)/(9a²-0,25m²)=24/(6a-m)

(3a+0,5m)/(a(3a-0,5m)) -(3a-0,5m)/(a(3a+0,5m)) +(36a)/(9a²-0,25m²)=24/(6a-m)

((3a+0,5m)²-(3a-0,5m)²)/(a(3a-0,5m)(3a+0,5m))

(36a)/(9a²-0,25m²)=24/(6a-m)

(9a²+3am+0,25m-9a²+3am-0,25m)/(a(3a-0,5m)(3a+0,5m)) +(36a)/(9a²-0,25m²)=24/(6a-m)

(6m)/((3a-0,5m)(3a+0,5m)) +(36a)/((3a-0,5m)(3a+0,5m))=24/(6a-m)

(6m+36a)/((3a-0,5m)(3a+0,5m))=24/(6a-m)

(12(3a+0,5m))/((3a-0,5m)(3a+0,5m))=24/(6a-m)

12/(3a-0,5m)=24/(6a-m)

(12·2)/((3a-0,5m)·2)=24/(6a-m)

24/(6a-m)=24/(6a-m)
