Answer:

3300

Explanation:

This can be worked out using PEMDAS:

First you solve in the PARENTHESIS:

(4 × 10³) – (7 × 10²)

Then, you look at the EXPONENTS:

(4 × 10³) = (4 × 1000)

(7 × 10²) = (7 × 100)

After that, look at the MULTIPLICATION:

(4000) - (700)

Since there is only subtraction left, subtract it:

3300
