To evaluate the expression \( 0.062 - (-0.023) \) and write the final answer in scientific notation, let's follow the steps below:
1. Identify the Numbers:
We have two decimal numbers to work with:
- \( 0.062 \)
- \( -0.023 \)
2. Understand the Operation:
The operation we need to perform is subtraction. However, subtracting a negative number is equivalent to adding the positive counterpart of that number. Thus, the expression \( 0.062 - (-0.023) \) simplifies to:
- \( 0.062 + 0.023 \)
3. Perform the Addition:
Now, let's add the two numbers:
- \( 0.062 + 0.023 = 0.085 \)
4. Express the Result in Scientific Notation:
Scientific notation requires expressing the number in the form of \( a \times 10^n \), where \( 1 \leq a < 10 \) and \( n \) is an integer.
The result \( 0.085 \) can be written in scientific notation. To do this, we move the decimal point two places to the right, giving us:
- \( 8.5 \times 10^{-2} \)
5. Final Answer:
The final answer in scientific notation is:
- \( 8.5 \times 10^{-2} \)
Therefore, the result of [tex]\( 0.062 - (-0.023) \)[/tex] in scientific notation is [tex]\( 8.5 \times 10^{-2} \)[/tex].
