Perform the indicated operations. Express the result in scientific notation. (5.7 * 105) + (4.6 * 106) - (2.9 * 105)

1.3905 * 10^4

Step-by-step explanation:

First you should multiply all the two numbers inside the parentheses

5.7 * 105=598.5

4.6 * 106=487.6

2.9 * 105=304.5

Now add the three numbers

598.5+487.5+304.5 = 1390.5

scientific notation: Put the decimal after the first digit. To find the exponent count the number of places from the decimal to the end of the number.

the answer in scientific notation: 1.3905 * 10^4
