Answer:
(2 x 10 ^-3) x (4 x 10 ^4)=8 x 10 ^1
Step-by-step explanation:
The mass of a single seed can be written as 0.002 = [tex]2*10^{-3}[/tex]
There are total of 4.3602 * 10 ⁴seeds in the jar
Total mass is the multiplication of these both numbers.
Since we want an estimate, we can use 4 instead of 4.3602 in the 2nd number.
The rule to multiply two numbers in scientific notation is:
[tex](a*10^{b} )*(c*10^{d} )=(a*c)*10^{b+d}[/tex]
So using this formula we multiply the 2 numbers and get answer as follows:
[tex](a*10^{b} )*(c*10^{d} )=(a*c)*10^{b+d} \\(2*10^{-3} )*(4*10^{4} )=(2*4)*10^{-3+4} \\=8*10^{1}[/tex]
