To solve the equation \( 0.0000486 + 3.67 \times 10^{-3} \), we first need to express \( 0.0000486 \) in scientific notation:
\[ 0.0000486 = 4.86 \times 10^{-5} \]
Now, we need to convert \( 4.86 \times 10^{-5} \) into a form with a power of ten that matches \( 3.67 \times 10^{-3} \). To do this, we rewrite \( 4.86 \times 10^{-5} \):
\[ 4.86 \times 10^{-5} = 0.0486 \times 10^{-3} \]
Now we can add them together:
\[ 0.0486 \times 10^{-3} + 3.67 \times 10^{-3} = (0.0486 + 3.67) \times 10^{-3} \]
Calculating the sum inside the parentheses:
\[ 0.0486 + 3.67 = 3.7186 \]
Now, we can express the final result:
\[ 3.7186 \times 10^{-3} \]
Thus,
\[ 0.0000486 + 3.67 \times 10^{-3} = 3.7186 \times 10^{-3} \]
So, the final answer is:
\[ 3.7186 \times 10^{-3} \]
