What is ten thousands 2 thousands 7 hundreds 8 tens 9 ones in standard form?

Step-by-step explanation:

Ten thousands = 10,000 * 1 = 10,000

2 thousands = 1000 * 2 = 2000

7 hundreds = 100 * 7 = 700

8 tens = 10 * 8 = 80

9 ones = 1 * 9 = 9

Adding them all:

=> 10,000 + 2,000 + 700 + 80 + 9

=> 12,789
