Answer 2

b) y= 8×7+8×5-8×4= 8(7+5-4)=8×8=8^2.

c) z= 27×95-27×68= 27(95-68)= 27×27= 27^2.

d) t= 27×26+27=27(26+1)= 27×27= 27^2

e) u= 27×28-27= 27(28-1)= 27×27= 27^2.

f) v=2^61-2^60= 2^60(2-1)= 2^60.

g) w= 3^37-2×3^36= 3^36(3-2)=3^36.

h) s= 3^19-3^18-3^18=3^18(3-1-1)=3^18.

i) (6^7)^8:(6^1)^2= 6^7×8:6^2=6^56:6^2=6^56-2=6^54.
