Answer with explanation:
Option A
\(1.\rightarrow 5.4 \times 10^4=5.4 \times 10000\\\\=54000\)
\(2.\rightarrow 5.4 \times 10^3=5.4 \times 1000\\\\=5400\)
\(3.\rightarrow 4.5 \times 10^4=4.5 \times 10000\\\\=45000\)
Option B
\(1.\rightarrow 5.4 \times 10^3=5.4 \times 1000\\\\=5400\)
\(2.\rightarrow 5.4 \times 10^4=5.4 \times 10000\\\\=54000\)
\(3.\rightarrow 4.5 \times 10^4=4.5 \times 10000\\\\=45000\)
Option C
\(1.\rightarrow 5.4 \times 10^3=5.4 \times 1000\\\\=5400\)
\(2.\rightarrow 4.5 \times 10^4=4.5 \times 10000\\\\=45000\)
\(3.\rightarrow 5.4 \times 10^4=5.4 \times 10000\\\\=54000\)
Option D
\(1.\rightarrow 4.5 \times 10^4=4.5 \times 10000\\\\=45000\)
\(2.\rightarrow 5.4 \times 10^3=5.4 \times 1000\\\\=5400\)
\(3.\rightarrow 5.4 \times 10^4=5.4 \times 10000\\\\=54000\)
⇒Option C ,shows number and exponents from least to greatest.
