481 = (4 x 100) + (8 x 10) + (1 x 1)
use a caculator and ask your teacher what expanded form is? aha , but number form it is, 4.4721359 OR its longer then that :}
20 squared = 20 x 20 = 400 400 in expanded form using exponents = (4 x 10^2) + (0 x 10^1) + (0 x 10^0)
20 squared = 400 = (4 x 100) + (0 x 10) + (0 x 1)
