Question

if 3 root 5 + root 125 is equal to 5.6 then what will be the value of root 80 + 6 root 5​

Answer 1

Answer:

7

Step-by-step explanation:

Given :-

3√5 + √125 = 5.6

3√5 + 5√5 = 5.6 ----------------( 5√5 = √125)

8√5 = 5.6

√5 = 5.6/8

√5 = 0.7

According to question:-

√80 + 6√5 = 4√5 + 6√5 = 10√5 ----------------(√80 = 4√5)

= 10√5

= 10x 0.7

= 7
