1. (x^3)^3 = x^(3*3) = x ^ 9
x^2 * x ^ 4 = x ^ ( 2+ 4) = x ^ 6
x ^ 9 / x ^ 6 = x^(9-6) = x ^ 3
2.(x^3)^5 = аналогично как и выше = x^15
(x^2)^4 * x^3= x^ (2*4+3) = x^11
x^15 / x^11 = x^4
3. (2^8 * 3^8 ) / 6 ^ 4
6 ^ 4 = 3 * 3 * 3 * 3 *2 * 2 * 2 * 2 = 3^4 * 2 ^4
(2^8 * 3^8 )/( 3^4 * 2 ^4) = 2 ^ 4 * 3 ^ 4
4. 12^6 / 3^5*4^5 = аналогично как и 3-е = 12
5. 36^3 * 15 ^ 2=18^6 * 15 ^2
18^6 - 18^4 = 18^2
(18^2 * 15^2 )/ 10 ^ 3 = (9 ^ 2 * 2 ^ 2 * 5 ^ 2 * 3 ^ 2)/2^3 * 5 ^ 3 = (9 ^ 2* 3 ^ 2) / 10 = 81* 9 / 10 = 72,9
6.(22^4 * 3^3)/(6^2 *121 ^ 2) = аналогично как и в 5-ом = 3 * 2 * 2 = 12
7. 3a + 2a(a - 3 )
a * ( 3 + 2a - 6)
8. 2x^2(x+1) + 2x^2*(x-3) =?
2x^2 * ( x+1 + x - 3)
2x^2 * (2x-2)
