Calculate or simplify the expression $$ 5.0 	imes 10^{4} - 6.8 	imes 10^{3} $$.
Calculate the value by following steps:
- step0: Calculate:
  $$5	imes 10^{4}-6.8	imes 10^{3}$$
- step1: Rewrite the expression:
  $$500	imes 10^{2}-68	imes 10^{2}$$
- step2: Collect like terms:
  $$\left(500-68ight)	imes 10^{2}$$
- step3: Subtract the numbers:
  $$432	imes 10^{2}$$
- step4: Evaluate the power:
  $$432	imes 100$$
- step5: Multiply the numbers:
  $$43200$$
The difference between the diameter of Neptune and the diameter of Mars is $$ 4.3 	imes 10^{4} \mathrm{~km} $$.
