6 × 10³ + 3 × 10⁴. Write in scientific notation.

Answer 1

To write the expression 6 × 10³ + 3 × 10⁴ in scientific notation, we need to combine the terms and rewrite it in the form a × 10ⁿ, where a is a number between 1 and 10, and n is an integer.

First, let's add the terms: 6 × 10³ + 3 × 10⁴ = (6 × 10³) + (3 × 10⁴) = 6000 + 30000 = 36000.

Now, we can see that 36000 can be expressed as 3.6 × 10⁴.

Therefore, 6 × 10³ + 3 × 10⁴ written in scientific notation is 3.6 × 10⁴.
