Answer:
7.677 x 10^1.
Explanation:
Here's how we convert the number:
Identify the non-zero digit to the left of the decimal point and move the decimal one position to the left without changing the value of the number. In this case, the number becomes 7.677.
Count the number of positions the decimal was moved, which is 0. Since the decimal wasn't shifted, the exponent of 10 will be 0.
Combine the leading non-zero digit and the remaining decimal places as the significand (7.677).
Add the exponent of 10 to indicate the magnitude of the number (7.677 x 10^0).
Therefore, 76.77 written in scientific notation is 7.677 x 10^1.
