Simplify by adding the expressions and putting your answer in Scientific Notation.

(5.6 x 10^−6
) + (1.5 x 10^−6
)

7.1 x 10^0

7.1 x 10^−6

8.4 x 10^−12

7.1 x 10^−12

To add these expressions, we first need to make sure they have the same exponent. We can do this by moving the decimal point to the left or right.

(5.6 x 10^−6) + (1.5 x 10^−6)

= 5.6 x 10^−6 + 0.15 x 10^−6 (move decimal point one place to the right)

= 6.1 x 10^−6

Now we can write this in scientific notation by moving the decimal point to the left and adjusting the exponent accordingly:

= 6.1 x 10^-6

Therefore, the simplified answer is 6.1 x 10^-6 in scientific notation.
