[tex]7 + 6 \times 7 = 7(1 + 6) = {7}^{2} \\ [/tex]
[tex]2 \times {3}^{14} + 25 \times {3}^{14} = {3}^{14} (2 + 25) = {3}^{14} \times {3}^{3} = {3}^{14 + 3} = {3}^{17} [/tex]
La C este (3+2) (5^15)=5x5^15=5^16
La D, 3^4 (3^2+18)= 3^4x (9+18) = 3^4•27=
=3^4•3^3=3^7
La E este 3^10 (3+6)= 3^10•9= 3^10•3^2=3^12
La f e 5^20(5-4)=5^20•1= 5^20

7+6*7=7*(1+6)=7*7=7²

2*3^14+25*3^14=3^14*(2+25)=3^14*3^3=3^30

3*5^15+2*5^15=5*5^15=5^16

3^6+18*3^4=9*3^4+18*3^4=27*3^4=3^3*3^4=3^7

3^11+6*3^10=3*3^10+6*3^10=9*3^10=3^2*3^10=3^12

5^21-4*5^20=5*5^20-4*5^20=5^20
