Question

√k²+3²=5 solve this step by step

Answer 1

Answer:

$\large\mathbb{ \green{ \bigstar GIVEN \bigstar}}$

$\sf \orange{ \sqrt{ {k}^{2} + 3 } = 5 }$

$\large\mathcal{ \green{Squaring \: \: both \: \: sides }}$

$\sf \orange{ \rightarrow (\sqrt{ {k}^{2} + 3 } )^{2} = {5}^{2} }$

$\sf \orange{ \rightarrow {k}^{2} + 3 = 25 }$

$\sf \orange{ \rightarrow {k}^{2} = 25 - 3 }$

$\sf \orange{ \rightarrow {k}^{2} = 22}$

$\sf \orange{ \rightarrow k = \pm \sqrt{22} }$

$\sf \green{ \rightarrow \boxed{ k = \pm \sqrt{22} }}$
