Answer 1

8+2*{16+2*[32+2(x-64)]}=8*3*5*121+16*3*25
8+2*{16+2*[32+2(x-64)]}=14520+1200
8+2*{16+2*[32+2(x-64)]}=15720
2*{16+2*[32+2(x-64)]}=15720-8
2*{16+2*[32+2(x-64)]}=15712
16+2*[32+2(x-64)]=15712/2
16+2*[32+2(x-64)]=7856
2*[32+2(x-64)]=7856-16
2*[32+2(x-64)]=7840
32+2(x-64)=7840/2
32+2(x-64)=3920
2(x-64)=3920
2(x-64)=3888
x-64=3888/2
x-64=1944
x=1944+64
x=2008

Answer 2

a)2^3+2×{2^4+2×[2^5+2×(2^6)]}=
8+2×[16+2×(32+2×64)=
8+2×[16+2×(32+128)=
8+2×(16+2×160)=
8+2×(16+320)=
8+2×336=
8+672=
680
b) 2^3×3×5×11^2+2^4×3×5^2=
8×3×5×121+16×3×25=
24×605+48×25=
14520+1200=
15720

Sper ca e bine!!! Succes!!!
