Answer

$4 \times 10^5$

Work Step by Step

Divide the corresponding parts. Then, put the expression in the form $a*10^n$, where a is a number that is greater than or equal to 1 but less than 10. $=\dfrac{3.6}{9} \times \dfrac{10^4}{10^{-2}} \\=0.4 \times 10^{4-(-2)} \\=0.4 \times 10^{4+2} \\=0.4 \times 10^{6} \\=4 \times 10^{6-1} \\=4 \times 10^5$
