Multiply. Write your answer in scientific notation. 100 · (2.3 × 10³)

To solve the problem ( 100 cdot (2.3 times 10^3) ), we can break it down into two parts:

1. First, multiply ( 100 ) by ( 2.3 ):

[

100 cdot 2.3 = 230

]

2. Then, we multiply the result by ( 10^3 ):

[

230 cdot 10^3

]

Next, we need to express ( 230 ) in scientific notation. We can write ( 230 ) as:

[

2.3 times 10^2

]

So, now substituting back into the equation:

[

2.3 times 10^2 cdot 10^3 = 2.3 times 10^{2+3} = 2.3 times 10^5

]

The final answer is:

A) ( 2.3 times 10^5 )
