d) 5 la put 11 - (6*5 la put 10 - 2*5 la put 10)

:((((((

Answer 1

a) (16*12^10 - 4 *12^10) : 12^11=
=12^10(16 - 4) : 12^11=
=12^10 *12 : 12^11=
=12^11 : 12^11=1

 b) 15^2 - ( 14 *15+15) : 15^2=
=15^2 - 15(14+1) : 15^2=
=15^2 - 15*15 : 15^2=
=15^2 - 15^2 : 15^2=
=15^2 - 1=
=225-1=224

c) 10^3 * 85 - 10^3 * 61 - 3000=
=10^3 * 85 - 10^3 * 61 - 10^3 *3=
=10^3 *21=
=21000

 d) 5^11 - (6*5^10 - 2*5^10)=
=5^11 - 5^10*(6 - 2)=
=5^11 - 5^10* 4=
=5^10(5 - 4)=
=5^10 *1=
=5^10
