Question

If 3√5 + √125 = 17.88, then find the value of
√80 + 6√5.​

Answer 1

Answer:

3√5 + √125 =  

3√5 + √25√5 =  

3√5 + 5√5 =  

8√5  

√80 + 6√5 =  

√16√5 + 6√5 =  

4√5 + 6√5 =  

10√5  

Let x = √80 + 6√5 and create a ratio.  

x/(10√5) = 17.88/(8√5)  

x/5 = 17.88/4  

x = 17.88(5)/4 = 22.35
