Can someone explain ?

See below.

Step-by-step explanation:

Using a calculator, find sqrt(2). You get:

Now to find

add

1.4142 + 1.4142 + 1.4142 to get 4.2426

The actual sum of

   equals approximately 4.2426

Now let's see what sqrt(6) is equal to.

Use a calculator again, and find sqrt(6).

As you can see, the correct sum, 4.2426, is very different from 2.4495, so sqrt(6) is not equal to the sum .

yes they are equal.

Step-by-step explanation:

instead of saying; squareroot 2 + sq2+ sq2 , it is more logic add the numbers and square root them once.

so, if you add them you will get 6 , which you will square root after.

NOTE that this only applies when you have same number inside the root sign.

hope you will understand.

according to this law, when unemployment goes up by 1%, gdp drops by 2%. in the question, unemployment rate goes from 2% to 5%, meaning unemployment goes up by 3%, so the gdp drops by 6%. thus the effect is a drop in gdp by 6%.
