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.
