Question

What is the result of adding 2.5 x 10^3 and 3.5 x 10^2

Answer 1

10^3 is 1000

So we have 2.5 x 1000 which is 2500

10^2 is 100

So we have 3.5 x 100 which is 350

Now we add 2500+350 and the answer is 2,850

Answer 2

Answer:

2850

Step-by-step explanation:

Start off by setting up your equation:

(2.5 x 10^3) + (3.5 x 10^2)

Work on one side first

2.5 x 10^3 = 2.5 x (10 x 10 x 10) = 2.5 x 1000 = 2,500

Work on the other side

3.5 x 10^2 = 3.5 x (10 x 10) = 3.5 x 100 = 350

Combine the two answers

2,500 + 350 = 2850
