Question

Multiply and give the answer in scientific notation: (2.3 x 10-3)(3 x 108)

Answer 1

Answer:

Scientific notation of $(2.3\times 10^{-3})\times (3\times 10^{8})$ is $6.9\times 10^{5}$ .

Step-by-step explanation:

As given the expression in the question be as follow .

$= (2.3\times 10^{-3})\times (3\times 10^{8})$

Simplify the above terms

$= 2.3\times 10^{-3}\times 3\times 10^{8}$

$= 2.3\times 3\times 10^{-3}\times 10^{8}$

Now by using the exponent property

$x^{a}\times x^{b} = x^{a + b}$

Thus apply this property in the above

$= 6.9\times 10^{-3+8}$

$= 6.9\times 10^{5}$

Therefore  scientific notation of $(2.3\times 10^{-3})\times (3\times 10^{8})$ is $6.9\times 10^{5}$ .

Answer 2

(2.3 x 10^-3)(3 x 10^8)
=(2.3 x 3)(10^-3 x 10^8)
= 6.9 x 10^5

hope it helps
