• B. 1054.362×10-4
• C. 10.54362×10-3
• D. 1054362×10-6

Answer 1

Note that we need to move 5 places to the right of the decimal in 1.054362 to get 105436.2.
$⟹105436.2=1.054362\times {10}^5$
Now, to get 0.1054362, we need to move 3 places to the left of the decimal in 1054.362.
$\therefore 0.1054362=1054.362\times {10}^{-4}$
Similarly, $0.01054362=10.54362\times {10}^{-3}$ and
$1.054362=1054362\times {10}^{-6}$
