# How do you write 12.13+1.5 in scientific notation?

Oct 11, 2017

$1.213 \times {10}^{1} + 1.5 \times {10}^{0}$

#### Explanation:

You would not really want to use scientific notation in this case - it is intended for very large or very small numbers.

But anyway, here it is:

$1.213 \times {10}^{1} + 1.5 \times {10}^{0} \text{ } \leftarrow$ the powers of 10 are different.

If you do want to add them, the powers must be the same:

$= 1.213 \times {10}^{1} + 0.15 \times {10}^{1} \text{ } \leftarrow$ now you can add them:

$= 1.363 \times {10}^{1}$
