a^11 - значит a в 11 степени ^ - значит в степени
1. a) =x^11 б)=5^17 в)=y^4 г)=(-2)^4=16 д)=3^4=81 е)=(-в)^6 ж)=2^(-5) * 2^5 =2^0 = 1
2. a) = 16x^4 y^4 z^2
б) = -2/5 x^6 y^3
3. a) =a^9 b^6 * 0.36a^2 b^4 = 0,36 a^11 b^10
б) = 81x^4 y^12 * (-1/27 xy^2) = -3x^5 y^14
4. a) x^2 y + y*x*y = x^2 y + xy^2 = xy(x+y)
б)2a*a^2 *3b + a*8c = 6a^3 *b + 8ac = 2a(3a^2 b + 4c)
в) 1.9x^3 - 2.9x^3 - x^3 = -x^3 - x^3 = -2x^3
г) 20xy + 5xy - 17xy = 8xy
5. (3a^2 + 7a -5) - (3a^2 +1 ) = 7a - 6
(5a+3) + (-2a^2 + a +7) = -2a^2 + 6a + 10
x^2 - 3xy + y^2 - (x^2 - y^2) = -3xy
(x+6y) + (3-6y) = x+3
(a-b+c) + (a-c) - (a-b-c) = a+c
6. -3x^2 + 5x +2 = -1/3 - 5/3 +2 = -6/3 + 2 = 0
