Question

6,2 * 10^2 +4,8 * 10^2 и представьте результат в стандартном виде

Answer 1

6,2*10^2+4,8*10^2=620+480=1100 или 1.1*10^3.

Answer 2

To add these two numbers, we need to make sure they have the same exponent. We can do this by rewriting 6.2 × 10^2 as 620 and 4.8 × 10^2 as 480:

620 + 480 = 1100

Now we can express the result in standard form by putting it in the form a × 10^n where 1 ≤ a < 10:

1100 = 1.1 × 10^3

Therefore, the sum of 6.2 × 10^2 and 4.8 × 10^2 in standard form is 1.1 × 10^3.
