The population of the city is given as 3.45×10 power of six and nearby city has a population of 1.3×10 power of five what is the sum of the population of the two cities in scientific notation what it be 3.58×10 power of six or 35.8+10 power of five or 4.75×10 power of 11 or last would it be 4.75×10 with the power of five

Answer 1

To find the sum of the populations of the two cities given in scientific notation, we first need to express both populations with the same exponent, and then we can add them together.

The populations are:

• City 1: \(3.45 \times 10^6\)
• City 2: \(1.3 \times 10^5\)

We can rewrite the second city's population to have the same exponent as the first city's:

\[ 1.3 \times 10^5 = 0.13 \times 10^6 \]

Now, we can add the populations:

\[ 3.45 \times 10^6 + 0.13 \times 10^6 = (3.45 + 0.13) \times 10^6 = 3.58 \times 10^6 \]

So, the sum of the populations of the two cities is:

\[ \boxed{3.58 \times 10^6} \]
