5. Упростите выражение:

1. \( x^{10} \cdot (x^{10} \cdot x^5) = x^{10} \cdot x^{10-5} = x^{10} \cdot x^5 = x^{10+5} = x^{15} \)
2. \( x^{18} \cdot (x^9 \cdot x^7) = x^{18} \cdot x^{9-7} = x^{18} \cdot x^2 = x^{18-2} = x^{16} \)
3. \( x^6 \cdot (x \cdot x^5) = x^6 \cdot x^{1+5} = x^6 \cdot x^6 = x^{6+6} = x^{12} \)
4. \( (x^4 \cdot x^3) \cdot (x^3 \cdot x^2) = x^{4+3} \cdot x^{3+2} = x^7 \cdot x^5 = x^{7-5} = x^2 \)
5. \( (x^{16} \cdot x^8) \cdot x^4 \cdot x^2 = x^{16-8} \cdot x^4 \cdot x^2 = x^8 \cdot x^4 \cdot x^2 = x^{8+4+2} = x^{14} \)
