Is there a Math wiz in the house?

square root of 20 minus square root of 125???
 
Why does that need a math genius it is simple arithmetic as there are no unknowns. The answer is -6.7082.
 
Then the answer is -6.71.
 
arent you suppose to break down sq root of 20 to sq root of 5 + 4

and the same with 125 to 100 + 25?
 
Find the real solution to the equation?

2
1/3x = 6
 
arent you suppose to break down sq root of 20 to sq root of 5 + 4

and the same with 125 to 100 + 25?

No, that would be incorrect. The square root of 20 is 4.472136 and the square root of 125 is 11.18034. It is basic arithmetic.
 
There are three kinds of people in this world: those who can do maths, and those that can't. :whatever:

I was born with a double digit :ninja:
 
This thread has established a calculator is often useful when doing maths.
