2an Method for Expand

a) 5×1,000 + 8×100 + 3×10 + 4×1

= 5×10³ + 8×10² + 3×10¹ + 4

b) 3×1000 + 2×100

= 3×10³ + 2×10²

c) 8×1000 + 0×100 + 7×10 + 0×1

= 8×10³ + 0×10² + 7×10¹ + 0

d) 4×1000 + 6×100 + 4×10 + 8×1

= 4×10³ + 6×10² + 4×10¹ + 8

e) 1×1000

= 1×10³

f) 3×1000 + 0×100 + 4×10 + 0

= 3×10³ + 0×10² + 4×10¹ + 0

g) 2×1000

= 2×10³

h) 7×1000 + 0×100 + 3×10 + 8×1
