The length of an object is measured as 86.7 centimeters. What is this measurement in scientific notation?

Question

A.
8,670 × 10^2 centimeters
B.
8.67 × 10^1 centimeters
C.
0.867 × 10^2 centimeters
D.
867 × 10^1 centimeters

Answer 1

To express 86.7 centimeters in scientific notation, we need to write it in the form of \(a \times 10^n\), where \(1 \leq a < 10\) and \(n\) is an integer.

The number 86.7 can be rewritten as:

\(8.67 \times 10^1\) (since moving the decimal point one place to the left decreases the exponent by 1).

So, the correct answer is:

B. 8.67 × 10^1 centimeters.
