ПОМОГИТЕ, УМОЛЯЮ.............

Answer 1

1)3,5×16-64=56-64=-8

2)x^15 ×x^13=x^(15+13) = x^28

x^15 ÷x^13=x^(15-13) = x^2

(x^15)^3 = x^(15×3) =x^45

3)-5,2c^3n^4×(-2)c^5×n^3= 5c^3n^4 × 2c^5×n^3= 10,4c^8n^7

4)(-65)^58 > (-25)^50

5)(4/3p^12a^6)^2=16/9a^12p^24

6)7x-28-10+5x+18=12x-20

12x-20=12x=20

7)9×8-3/23=72-3/23=69/23=3
