(1.5 × 10 - 7) × (3.6 × 1015) ÷ (1.2× 10 - 3) = 3248
Step-by-step explanation:
The order of operations to solve a problem is:
- Brackets
- Exponents
- Multiplication or division
- Addition or subtraction
The problem is:
(1.5 × 10 - 7) × (3.6 × 1015) ÷ (1.2× 10 - 3)
At first solve the operations inside all the brackets
In the bracket 1.5 × 10 - 7 we must make multiplication at first then subtract
∵ 1.5 × 10 = 15
∵ 15 - 7 = 8
∴ (1.5 × 10 - 7) = 8
In the bracket 3.6 × 1015
∵ 3.6 × 1015= 3654
∴ (3.6 × 1015) = 3654
In the bracket 1.2 × 10 - 3 we must make multiplication at first then subtract
∵ 1.2 × 10 = 12
∵ 12 - 3 = 9
∴ (1.2 × 10 - 3) = 9
Now replace all the brackets by their answers
∴ (1.5 × 10 - 7) × (3.6 × 1015) ÷ (1.2× 10 - 3) = 8 × 3654 ÷ 9
- From the ordered above multiply at first then divide
∵ 8 × 3654 = 29232
∵ 29232 ÷ 9 = 3248
(1.5 × 10 - 7) × (3.6 × 1015) ÷ (1.2× 10 - 3) = 3248
