Answer:
3300
Step-by-step 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
