To solve the equation \( 3.75 \times 10^? = 0.0000375 \), we need to express \( 0.0000375 \) in scientific notation.
First, we recognize that \( 0.0000375 \) can be expressed as:
\[ 0.0000375 = 3.75 \times 10^{-5} \]
We can verify this:
- Move the decimal point in \( 3.75 \) left 5 times to convert it to \( 0.0000375 \).
Now we equate the two expressions:
\[ 3.75 \times 10^? = 3.75 \times 10^{-5} \]
Since both sides have \( 3.75 \), we can simplify by removing it from both sides:
\[ 10^? = 10^{-5} \]
Therefore, \( ? = -5 \).
Thus, the correct answer is:
-5
