Answer 1

Ответ:

1) (a+2)/(3a³) - (a²-1)/(a⁵) = (a³+2a²)/(3a⁵) - (3a²-3)/(3a⁵) = (a³+2a²-3a²+3)/(3a⁵) =

= (a³-a²+3)/(3a⁵)

2) 5/(2b²) + (1-b⁴)/(3b⁶) = (15b⁴)/(6b⁶) + (2-2b⁴)/(6b⁶) = (15b⁴+2-2b⁴)/(6b⁶) =

= (13b²+2)/(6b⁶)

3) (7-m)/(6m³) - (3+2m)/(2m²) = (7-m)/(6m³) - (9m+6m²)/(6m³) =

= (7-m-9m-6m²)/(6m³) = (-6m²-10m+7)/(6m³)

4) (2-3p²)/(15p⁶) + (4+p)/(10p⁴) = (4-6p²)/(30p⁶) + (12p²+3p³)/(30p⁶) =

= (4-6p²+12p²+3p³)/(30p⁶) = (3p³+6p²+4)/(30p⁶)
