The expression given to us is [tex] 3.0\times 10^3-2.0\times 10^2 [/tex]. We know that [tex] 3.0\times 10^3=3000 [/tex] and [tex] 2.0\times 10^2=200 [/tex].
Therefore, the given expression can be written as:
[tex] 3.0\times 10^3-2.0\times 10^2=3000-200=2800 [/tex]
Which again can be rewritten as: [tex] 2.8\times 10^3 [/tex]
Thus, the evaluation of the given expression [tex] 3.0\times 10^3-2.0\times 10^2 [/tex] gives us: 2800 or [tex] 2.8\times 10^3 [/tex].
