1. $$a^{23}: a^4 = a^{23-4} = a^{19}$$

Ответ: $$a^{19}$$

2. $$b^{12}: b^5: b = b^{12-5-1} = b^6$$

Ответ: $$b^6$$

3. $$c^8: c^7: c = c^{8-7-1} = c^0 = 1$$

Ответ: $$1$$

4. $$15^{18}: 15^{10}:15^2 = 15^{18-10-2} = 15^6$$

Ответ: $$15^6$$

5. $$0.5^{14}: 0.5^2 = 0.5^{14-2} = 0.5^{12}$$

Ответ: $$0.5^{12}$$

6. $$(a-2)^5: (a-2)^2 = (a-2)^{5-2} = (a-2)^3$$

Ответ: $$(a-2)^3$$

7. $$(\frac{1}{2})^{25} : (\frac{1}{2})^2 = (\frac{1}{2})^{25-2} = (\frac{1}{2})^{23}$$
