The expression written in scientific notation is "73.4 times 10^5".
To determine which expression is written in scientific notation, we need to identify the expression that follows the correct format of a number multiplied by a power of 10.
Let's analyze each expression in turn:
1. Image with alt text: 73.4 times 10^5
This expression is written in scientific notation because it consists of a number (73.4) multiplied by 10 raised to a power (5). Therefore, this expression is in scientific notation.
2. Image with alt text: 0.09 times 10^7
This expression is also written in scientific notation because it follows the same format as the previous expression. There is a number (0.09) multiplied by 10 raised to a power (7). Thus, this expression is in scientific notation.
3. Image with alt text: 80 times 10^3
This expression is not written in scientific notation because the number (80) is not in between 1 and 10. In scientific notation, the coefficient should be between 1 and 10, while the exponent adjusts the magnitude of the number. Therefore, this expression is not in scientific notation.
So, based on the analysis, the expressions in scientific notation are the first two options:
1. Image with alt text: 73.4 times 10^5
2. Image with alt text: 0.09 times 10^7
