Plz help​

Answer 1

$\sqrt{121} = 11$

$\sqrt{81} = 9$

Answer 2

Answer:

Step-by-step explanation:

Given that,

√81 + 3√64 + 2x = 4√121

⇒9 + 3 ( 8 ) + 2x = 4 ( 11 ) ( ∵√81 = 9, √64=8 and √121= 11 )

⇒ 9 + 24 + 2x = 44

⇒ 33 + 2x = 44

⇒ 2x = 44 - 33 (∵transposing )

⇒ 2x = 11

⇒ x = 11/2 is the answer. (∵transposing )
