To write 0.489 in standard form, you express it in the form of ( a \times 10^n ), where ( 1 \leq a < 10 ) and ( n ) is an integer. For 0.489, you can rewrite it as ( 4.89 \times 10^{-1} ) since moving the decimal point one place to the right increases the exponent by -1. Thus, the standard form of 0.489 is ( 4.89 \times 10^{-1} ).
