Answer 1

2^3 x 3^2 + 25^0 x 11^2 - 4^6 =
8x9+1x121-256=
72+121-256=
193-256=
-63

1+{2+ [3x (4+5) -6+7x8] - 9}=
1+[2+ (3 x 9 - 6+56) -9]=
1+[ 2+ (27-6+56) -9]=
1+(2+ 77-9) =
1+70=
71

9x {[ 8+7 x(6+5)] x4 -3}+ 2=
9 x [( 8+7 x 11) x 4-3]+2=
9x [(8+ 77) x 4-3] +2=
9x (85 x 4 - 3) +2=
9 x ( 340-3 )+2=
9 x 337+ 2=
3033+2 =
3035
