Simplify using BODMAS: Bracket – Of – Division – Multiplication – Addition – Subtraction

\(\sqrt {\left( {150 - x} \right)} = \sqrt {\left( {148 - \sqrt {729} } \right)}\)

\(\Rightarrow \sqrt {\left( {150 - x} \right)} = \sqrt {\left( {148 - 27} \right)}\)

⇒ 150 – x = 121

⇒ x = 150 – 121

∴ x = 29
