Question

What is the result of adding 2.5x10^3 and 3.5x10^2

Answer 1

2.85x10^3 that is what the answer is

Answer 2

Answer:

sum = $2.85*10^3$

Step-by-step explanation:

Given are two numbers in scientific notation and we have to add them

The numbers are

$1) 2.5*10^3\\ 2) 3.5*10^2$

As such we cannot add as these are numbers not like terms.

We can either make both with same powers of x and add.

$1) 2.5*10^3\\\\ 2) 3.5x10^2=0.35*10^3$

Now we can add since both are like terms.

Adding we get

sum = $2.85*10^3$
