Question

7 root 48 - root 72 - root 27 + 3 root 2 simplified​

Answer 1

Answer:39.04

Step-by-step explanation:Given

7 root 48 - root 72 - root 27 + 3root 2

For solving this problem u need to first find out the roots of all

For getting roots of non perfect square u can simply break it and put it in formula given below

Root (x +or - y) = root x +or- y/2root x

Here for root 48

root 48 = root(49-1)

= root 49 - 1/2*root49 { here x is 49 and y is 1}

= 7 - 1/2*7

= 7 - 0.07

=root 48 = 6.9

Similarly get all the roots

And put it in the question

7(6.93) - (8.48) - (5.19) + 3*(1.4)

= 48.51 - 8.48 - 5.19 + 4.2

= 39.04(approx)
