Answer 2

Answer:

first square = 3.6 x $10^{-1}$

Step-by-step explanation:

They are all multiplying so there is no need for parenthesis

(3.8 * 10³) * (9.4 * $10^{-5}$)

3.8 * 10³ * 9.4 * $10^{-5}$
35.72 * $10^{-2}$

35.72 =~ 36

Everytime you elevate a number, it's the same as...
3 * 10² = 100 * 3 = 300

0.3 * 10³ = 1000 * 0.3 = 300

so then...

36 *      $10^{-2}$ = 3.6 * $10^{-1}$
