Required knowledge for question 1 and 2 :-

Place value => Period place of the number

Solution of question 1 :-

Place value of both the 3's in the number 8363 => 300 and 3

Sum of 300 and 3 => 300 + 3 => 303

Therefore, the sum of place values of both the 3's in the number 8363 is 303.

Solution of question 2 :-

Place value of 4 and 7 in the number 84037 => 400 and 7

Difference of 400 and 7 => 400 - 7 => 393

Therefore, the difference of place values of 4 and 7 in the number 84037 is 393.

Solution of question 3 :-

3 × 10⁴ + 9 × 10³ + 4 × 10² + 5× 10¹

=> 3 × 10000 + 9 × 1000 + 4 × 100 + 5 × 10 + 0 × 1

=> 30000 + 9000 + 400 + 50 + 0

=> 39450

Therefore, 3 × 10⁴ + 9 × 10³ + 4 × 10² + 5 × 10¹ in standard form is 39450.
