Given that √3  = 1.7321 , find correct to 3 places of decimals , the value of √192 - 1 / 2√48 - √75

Step-by-step explanation:

the value of root three is given already so the question is asking you to round it of to the nearest 1000 which means there should be three numbers after the decimal point.

Which 2 sides ? 
Pythagorean Theorem = a^2 + b^2 = c^2 

which side do you need? 

The hypotenuse is the longest side. 

for example 7^2 + 11^2 = c^2 
then 
49 + 121 = 170 

Therefore, the answer is the square root of 170. 

But you may have 
7^2 + b^2 = 11^2 which would be 49 + b^2 = 121 

so b would be the square root of 72 

Can you show me the exact problem??
