Question

Compute 4.659×104−2.14×104. Round the answer appropriately.

Express your answer as an integer using the proper number of significant figures (e.g. 12300).

Answer 1

To compute 4.659×104−2.14×104, the first step is the factorization. That is as follows:4.659×104−2.14×104= 10^4.(4.659−2.14), the next step is to compute 4.659−2.14=2.51, so 10^4.(4.659−2.14)=2.51x10^4=2.51x 10000 (because10^4=10000), the last calculus is 2.51x 10000=25100, the final answer is 25,000.Hope this helps.

Answer 2

Answer is: proper number of significant figures is 25190.00.

10⁴ = 10×10×10×10.

10⁴ = 10000.

1) 4.659×10⁴ = 4.659×10000.

4.659×10⁴ = 46590.

2) 2.14×10⁴ = 2.14×10000.

2.14×10⁴ = 21400.

3) 4.659×10⁴ - 2.14×10⁴ = 46590 - 21400.

4.659×10⁴ - 2.14×10⁴ = 25190 (2.519×10⁴).

An integer is a number that can be written without a fractional component.
