Let's choose the numbers 1.95x10^6 and 2.56x10^-2 to add together.
1.95x10^6 + 2.56x10^-2
First, we need to make sure the exponents are the same. We can rewrite 1.95x10^6 as 195x10^4.
Now we can add:
195x10^4 + 2.56x10^4
= 197.56x10^4
Finally, we can convert 197.56x10^4 back to scientific notation:
197.56x10^4 = 1.9756x10^6
So, 1.95x10^6 + 2.56x10^-2 = 1.9756x10^6.
1.95x10^6 + 2.56x10^-2
First, we need to make sure the exponents are the same. We can rewrite 1.95x10^6 as 195x10^4.
Now we can add:
195x10^4 + 2.56x10^4
= 197.56x10^4
Finally, we can convert 197.56x10^4 back to scientific notation:
197.56x10^4 = 1.9756x10^6
So, 1.95x10^6 + 2.56x10^-2 = 1.9756x10^6.
