Вариант I
1) \(x^6 * x^8 = x^{6+8} = x^{14}\)
2) \(x^8 : x^6 = x^{8-6} = x^2\)
3) \((x^6)^8 = x^{6*8} = x^{48}\)
4) \(\frac{(x^4)^3 * x^2}{x^9} = \frac{x^{4*3} * x^2}{x^9} = \frac{x^{12} * x^2}{x^9} = \frac{x^{12+2}}{x^9} = \frac{x^{14}}{x^9} = x^{14-9} = x^5\)
Вариант II
1) \(a^7 * a^4 = a^{7+4} = a^{11}\)
2) \(a^7 / (a^3) = a^{7-3} = a^4\)
3) \((a^7)^4 = a^{7*4} = a^{28}\)
4) \(\frac{(a^3)^2}{a} = \frac{a^{3*2}}{a} = \frac{a^6}{a} = a^{6-1} = a^5\)
