Răspuns:

Explicație pas cu pas:

^=radical

1)=2^3+3^2-15^2+20^3+3^2-12^3=10^3-9^2

2)=2x-5y-15x+20y+4x-y=-9x+140

3)=12^2-6^6-7^2+4^6=5^2-2^6

4)=2xla puterea 2-8x+xla puterea2-7x+10-6xla puterea 2-12x-15=-4 xla puterea 2-27x-5

5)=x la puterea 2+2x+1

6)=4x la puterea 2-4x+1

7)=25x la puterea 2-4+4xla puterea 2+4x+1-x la puterea 2-3x+9=28x la puterea 2+x+6

8)=3-10^3+25=28-10^3

9)=5+4^5+4=9+4^5

10)4×3-2=10
