Question

Evaluate the given expression​

Answer 1

Answer:

5.399

Step-by-step explanation:

15/( root 10 + root 20 + root 40 - root 5 - root 80) ( root 5 = 2.236)

15/( root 10 + root 4*5 + root 4*10 - root 5 - root 16*5)   (root 10 = 3.162)

15/( root 10 + 2 root 5 + 2 root 10 - root 5 - 4 root 5)

15/( 3 root 10 - 3 root 5 )

15/( 3*3.162 - 3* 2.236)

15/(9.486 - 6.708)

15/( 2.778)

5.399
