Question

Помогите пожалуйста умоляю а то мозги уже не варят

Answer 1

1. = (128:10 - 0,008*100):0,0625 = 12,8-0,8:0.0625 = 12-0,0625 = 11,9375

2. a) = -y^35 * y^36 = y

б) = a^8/a^20 = a^-12

3. = -1.5a^15*b^25*c^5 * 32a^4*c^6 = -48*a^19*b^25*c^11

4. -5x^2-7x+11=9+4x-5x^2

-11x+2=0

11x=2

x=2/11

5. 1) = (7^10*7^12)/7^21 = 7^22/7^21 = 7

2) = (2^10*7^10)/(2^8*7^10) = 2^2 = 4

3) = (4^6*7^4)/(7^6*4^4) = 4^2/7^2 = 16/49
