Answer:
5.088⋅10^10
Explanation:
First, we will put a decimal point at the end of number 50880000000.
In order to write number 50880000000. in scientific notation we need to move the decimal point from its current location (black dot) to the new position (red dot).
5.0880000000.
So, we need to move decimal point 10 places to the right.
This means that the power of 10 will be positive 10.
Now we have that the
Number part = 5.0880000000 ( which can be written as 5.088 ) and
Exponent part = 10

While experimental research has several advantages, including: investigating the effect of one variable on another, and the ability to control and eliminate confounding variables, it also has one major disadvantage. This disadvantage is known as: <em>lack of ecological validity</em>.
Lack of ecological validity means that the findings of research study might not be generalizable to real-life settings, and might only apply to laboratory settings. To avoid the problem of ecological validity, and to increase the validity of an experimental research study, a study should be conducted in natural settings when possible.
