Correct Answer is : −30^i+32^j−9^k

-0.30\stackrel{\^}{{i}}+0.32 \stackrel{\^}{{j}}-0.09 \stackrel{\^}{{k}}

-300 \stackrel{\^}{{i}}+320 \stackrel{\^}{{j}}-90 \stackrel{\^}{{k}}

-30 \stackrel{\^}{{i}}+32\stackrel{\^}{{j}}-9 \stackrel{\^}{{k}}

-3.0\stackrel{\^}{{i}}+3.2 \stackrel{\^}{{j}}-0.9 \stackrel{\^}{{k}}
