Solution
Solution Steps
To express the number \(-6.31088724 \times 10^{-30}\) in scientific notation with three significant digits, we need to round the coefficient to three significant figures. The number is already in scientific notation, so we only need to adjust the precision of the coefficient.
Step 1: Identify the Original Number
The original number given is \( -6.31088724 \times 10^{-30} \).
Step 2: Round to Three Significant Digits
To express this number in scientific notation with three significant digits, we round the coefficient \( -6.31088724 \) to three significant figures. This gives us \( -6.31 \).
Step 3: Write in Scientific Notation
The rounded number can now be expressed in scientific notation as:
\[
-6.31 \times 10^{-30}
\]
Final Answer
Thus, the number \( -\frac{1}{2^{97}} \) written in scientific notation with three significant digits is
\[
\boxed{-6.31 \times 10^{-30}}
\]
