Question

If square root of (x+11)=5,find the real value of x

Answer 1

Answer:

14

Step-by-step explanation:

√ x+11 = 5

squaring on both sides,

x + 11 = 25

x = 25 - 11

x = 14

Answer 2

Answer:

Step-by-step explanation:

Given that,

√( x + 11 ) = 5

⇒ Squaring on both sides, we get

⇒ [ √ ( x + 11 ) ]² = ( 5 )²

⇒ x + 11 = 25 (∵ square root and square are cancelled )

⇒ x = 25 - 11 (∵transposing )

⇒x = 14 is the answer.
