what is the result of adding (2.5x10^3)+(3.5x10^2) ?
2.5E3
+0.35E3
=========
2.82E3 which rounds to 2.8E3
To add numbers written in scientific notation, you have to ensure that the exponents are the same. In this case, you can rewrite the numbers as follows:
(2.5 x 10^3) + (3.5 x 10^2)
To make the exponents the same, you can rewrite 3.5 as 0.35 x 10^3:
(2.5 x 10^3) + (0.35 x 10^3)
Now that the exponents are the same, you can add the numbers:
2.5 + 0.35 = 2.85
The result is 2.85 x 10^3.
To add two numbers written in scientific notation, you need to make sure both numbers have the same exponent (power of 10). Here's how you can perform the addition:
Step 1: Rewrite the numbers with the same exponent.
(2.5x10^3) = (2.5x10^3)
(3.5x10^2) = (0.35x10^3)
Step 2: Now, you can add the numbers: 2.5 + 0.35 = 2.85
Step 3: Keep the common exponent (10^3) in the final result.
Therefore, the result of adding (2.5x10^3) + (3.5x10^2) is 2.85x10^3.
