Ответ:

а t⁷ - t⁵ = t^(7-5) = t²

б x¹⁰ : x⁷ = x^(10-7) = x³

Объяснение:

а) Щоб відняти однакові бази зі степенями, потрібно відняти степені.

t⁷ - t⁵ = t^(7-5) = t²

б) Щоб поділити однакові бази зі степенями, потрібно відняти степені.

x¹⁰ : x⁷ = x^(10-7) = x³

lizabusy09: Степени вычитаются только при делении. В первом будет:
lizabusy09: t⁷-t⁵=t⁵(t²-1)=t⁵(t+1)(t-1)
moneydans16: це не правильна відповідь
murderfunder: правильно.
