What is the product expressed in scientific notation?

[tex]0.00043 \times\left(6.5 \times 10^8\right)[/tex]

A. [tex]2.795 \times 10^3[/tex]
B. [tex]2.795 \times 10^6[/tex]
C. [tex]2.795 \times 10^5[/tex]
D. [tex]2.795 \times 10^4[/tex]



Answer :

To solve the given problem [tex]\(0.00043 \times (6.5 \times 10^8)\)[/tex] and express the product in scientific notation, follow these steps:

1. Understand the Multiplication: We need to multiply [tex]\(0.00043\)[/tex] by [tex]\(6.5 \times 10^8\)[/tex].

2. Perform the Multiplication: When we multiply [tex]\(0.00043\)[/tex] and [tex]\(6.5 \times 10^8\)[/tex], we obtain:
[tex]\[ 0.00043 \times 6.5 = 0.002795 \][/tex]
Next, include the magnitude [tex]\(10^8\)[/tex] to get:
[tex]\[ 0.002795 \times 10^8 = 279500.0 \][/tex]

3. Convert to Scientific Notation: The number [tex]\(279500.0\)[/tex] can be written in scientific notation by moving the decimal point five places to the left, resulting in:
[tex]\[ 2.795 \times 10^5 \][/tex]

Therefore, the product of [tex]\(0.00043 \times 6.5 \times 10^8\)[/tex] expressed in scientific notation is:
[tex]\[ 2.795 \times 10^5 \][/tex]

Thus, the correct answer is:
[tex]\[ \boxed{2.795 \times 10^5} \][/tex]
