номер 4. 5. 6. Помогите. Плис

Ответ:

4.1 9*(-1/3)+5= -3 + 5 = 2

4.2 (4-5*1/5)^2=(4-1)^2 = 3^2=9

5.1  1.6a^6b^2*(-0.5a^4b^4)^3 = -0.2a^18b^14

5.2 (x^2)^6*x^12/x^10 = x^12*x^12/x^10=x^24/x^10 = x^14

6.1 8^2*4^5/16^3=2^6*2^10/2^12=2^10/2^6=2^4=16

6.2 (1*(1/9))^4*(9/10)^3=1*(1/9)*1^3=1(1/9)= 1.1
