Final answer:
The result of 5.4×10^4 −3.1×10^4 is 2.3×10^4 , which is 23,000.
Step-by-step explanation:
To evaluate 5.4 × 1 0^4 − 3.1 × 1 0^4, you can subtract the coefficients while keeping the exponent (since the terms have the same exponent, which is 10^4 ):
( 5.4 − 3.1 ) × 1 0^4
Now, calculate the numerical part:
2.3 × 1 0^4
So, 5.4 × 10^4 − 3.1 × 1 0^4 is equal to2.3×10^4 is the answer after subtracting the numbers in scientific notation.
It's essentially saying that the result is 2.3 times 10^4 or 23,000. This is a common approach when working with very large or very small numbers, as scientific notation helps express them in a concise and manageable form.
