Question 219038: Grade the following problem:;
Perform the indicated operations:
√[50] + 2√[32] – √[8]
=sq rt [(5)(10)] +2 sq rt [(8)(4)- sq rt [(2)(4)]
=sq rt [5]sq rt [10]+2 sq rt[4] sq rt[4] –sq rt[2] sq rt[4]
=(5+2)sq rt[10]
=7 sq rt[10]

SQRT[50] + 2SQRT[32] – SQRT[8]
SQRT[25*2]+2SQRT[16*2]-SQRT[4*2]
5SQRT2+2*4SQRT2-2SQRT2
(5+8-2)SQRT2
(11)SQRT2
11*1.414=15.556 ANS.
