so we know that when you multiply it together it equals 78,744 so we move it back 4. which brings us to 7.87 then multiply it by 10^4 which is 44.
so the answer is 7.87 * 10^4
hope i was able to help plz message me if u need anymore help or if u dont quite understand.
Answer: [tex]7.87\times 10^4[/tex]
[tex] (386)(204)=386 \times 204 =78744 [/tex]
In scientific notation, a number is written between 1 and 10 multiplied by a power of 10.
[tex] m\times 10^n[/tex] where m lies between 1 and 10 and n is an integer.
So, 78744 can be written in scientific notation as : [tex]7.8744 \times 10^4[/tex]
Significant digits in the answer depends on the least significant digits in the multipliers. The significant digits in the multipliers is 3. Therefore, the answer must contain 3 significant digits.
Answer: [tex]7.87 \times 10^4[/tex]
