0.0000486+3.67×10^−3= ____×10^−3

1 answer

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:

\[ 3.7186 \times 10^{-3} \]
