Given: 38400 We are asked to expand the given number. Let us first write the number in place value chart. Ten Thousands Thousands Hundreds Tens Ones ( 10000 ) ( 1000 ) ( 100 ) ( 10 ) ( 1 ) 3 8 4 0 0 Now, by multiplying each digit with their respective place values, we get 38400 = 3 × 10000 + 8 × 1000 + 4 × 100 + 0 × 10 + 0 × 1 = 30000 + 8000 + 400 + 0 + 0 = 30000 + 8000 + 400 Hence, the expanded form of 38400 is 30000 + 8000 + 400 .

Given: 77888 We are asked to expand the given number. Let us first write the number in place value chart. Ten Thousands Thousands Hundreds Tens Ones ( 10000 ) ( 1000 ) ( 100 ) ( 10 ) ( 1 ) 7 7 8 8 8 Now, by multiplying each digit with their respective place values, we get 77888 = 7 × 10000 + 7 × 1000 + 8 × 100 + 8 × 10 + 8 × 1 = 70000 + 7000 + 800 + 80 + 8 Hence, the expanded form of 77888 is 70000 + 7000 + 800 + 80 + 8 .

Given: 20050 We are asked to expand the given number. Let us first write the number in place value chart. Ten Thousands Thousands Hundreds Tens Ones ( 10000 ) ( 1000 ) ( 100 ) ( 10 ) ( 1 ) 2 0 0 5 0 Now, by multiplying each digit with their respective place values, we get 20050 = 2 × 10000 + 0 × 1000 + 0 × 100 + 5 × 10 + 0 × 1 = 20000 + 0 + 0 + 50 + 0 = 20000 + 50 Hence, the expanded form of 20050 is 20000 + 50 .
