Final answer:
The value of the expression 8.3 times 10⁴ - 2.5 times 10³ - 1.9 times 10⁴ is 61,500.
Step-by-step explanation:
To find the value of the expression 8.3 times 10⁴ - 2.5 times 10³ - 1.9 times 10⁴, we can subtract the products of the numbers and their exponents.
First, let's multiply the numbers and their exponents:
8.3 × 10⁴ = 83,000
2.5 × 10³ = 2,500
1.9 × 10⁴ = 19,000
Next, subtract the products:
83,000 - 2,500 - 19,000 = 61,500
Therefore, the value of the expression is 61,500.
