Question

Perform the following operation
and express the answer in
scientific notation.
3.4000x 10-6 +5.7000x 10-3

Answer 1

Explanation:

3.4000x 10-6 +5.7000x 10-3

$3.4000 \times {10}^{ - 6} = 3.4 \times {10}^{ - 6}$

$5.7000 \times {10}^{ - 3} = 5700 \times {10}^{ - 6}$

now we can add them

$3.4 + 5700 = 5703.4 \\ = 5703.4 \times {10}^{ - 6}$

$= 5.7034 \times {10}^{ - 3}$
