1) = (а⁻⁸ * а⁻⁶ ) / а⁻³ = а⁻¹⁴ / а⁻³ = а⁻¹¹ или 1/а¹¹
2) = (а⁻⁶ / b⁻⁹ ) * a⁵ * b⁻⁸ = a⁻¹ *b¹ = b/a
3) = (1 * 8⁻⁴) / ((2*8)⁻² * 2¹) = 8⁻⁴ / (2⁻² * 8⁻² *2¹) = 8⁻² / 2⁻¹ = (4*2)⁻² / 2⁻¹ = (4⁻² * 2⁻²) / 2⁻¹ = 4⁻² * 2⁻¹= 1/16*1/2 = 1/32
4) = -12х²+4х
5) = 12х⁴-6х² - 4х²+2 = 12х⁴-10х²+2
6) = 4 - 1 + 1/4 :3 = 3+1/12 = 3¹/₁₂
7) = -3,78а⁴с⁵k²s²
8) = 6a²c * (-2⁴ a⁴c⁴) = 6 a⁶c⁵ * 1/16 = 0,375a⁶c⁵
