(h) 26999.

Solution:

(a)

The expanded form of 232 = 200 + 30 + 2

(b)

The expanded form of 4180 = 4000 + 100 + 80 + 0

(c)

The expanded form of 27811 = 20000 + 7000 + 800 + 10 + 1

(d)

The expanded form of 82994 = 80000 + 2000 + 900 + 90 + 4

(e)

The expanded form of 10073 = 10000 + 70 + 3

(f)

The expanded form of 43710 = 40000 + 3000 + 10

(g)

The expanded form of 61639 = 60000 + 1000 + 600 + 30 + 9

(h)

The expanded form of 26999 = 20000 + 6000 + 900 + 90 + 9
