Evaluate. Express your answer in scientific notation.
3, point, 4, times, 10, to the power minus 7 , plus, 3, point, 3, times, 10, to the power minus 7

3.4×10^-7 + 3.3×10^-7 = 6.7×10^-7
To evaluate the expression, we add the two numbers together:
3.4 × 10^-7 + 3.3 × 10^-7
This can be written in scientific notation as:
(3.4 + 3.3) × 10^-7
Adding the numbers together:
6.7 × 10^-7
Therefore, the expression evaluates to:
6.7 × 10^-7
To evaluate the given expression and express the answer in scientific notation, we can sum up the two terms:
3.4×10^-7 + 3.3×10^-7
To simplify this, we add the numerical coefficients and keep the same exponent:
(3.4 + 3.3) × 10^-7
Adding the numerical coefficients, we get:
6.7 × 10^-7
Therefore, the evaluated expression in scientific notation is 6.7×10^-7.
