Answer: [tex]1.032 \times 10^8[/tex]
You'll have 1.032 in the first box and 8 in the second box.
=====================================================
Work Shown:
[tex]A = 4.3 \times 10^2\\\\B = 2.4 \times 10^5\\\\A * B = (4.3 \times 10^2) * (2.4 \times 10^5)\\\\A * B = (4.3*2.4) \times (10^2*10^5)\\\\A * B = 10.32 \times 10^{2+5}\\\\A * B = (1.032 \times 10^1) \times 10^7\\\\A * B = 1.032 \times (10^1*10^7)\\\\A * B = 1.032 \times 10^{1+7}\\\\A * B = \boldsymbol{1.032 \times 10^8}\\\\[/tex]
When expanded out, the number [tex]1.032 \times 10^8[/tex] turns into [tex]103,200,000[/tex] which is just a bit over 103 million.
As the steps above show, we multiply the numbers out front to get 4.3*2.4 = 10.32 which then converts to [tex]1.032\times10^1[/tex]. The exponential terms, when multiplied, will have the exponents add. The rule is [tex]a^b*a^c = a^{b+c}[/tex]
The first number 1.032 of the answer above is between 1 and 10, excluding 10. So it's a sign that the value is in scientific notation. That's why I converted the 10.32 to [tex]1.032\times10^1[/tex]
