The best estimate for (2.8 x 10^3)(4.1 x 10^6) written in scientific notation will be 1.5 x 10^10.
The number is written in the form a [tex]\times 10^b[/tex] where we have [tex]1 \leq a < 10[/tex]
The number b shows the order, which is the most important figure for which scientific notation is used.
Its value in terms of the power of 10 is known, which helps in easy comparison of quantities differing by a large value.
We have given an expression as
[tex](2.8 \times 10^3)(4.1 \times10^6)\\= 2.8 \times4.1\times10^9\\= 11.48 \times10^9\\= 1.148 \times10^{10}\\= 1.15 \times 10^{10}[/tex]
Therefore, The closest answer will be C.
