Question

(-2i^ -3k^)+(3j^)=. ?​

Answer 1

$\tt \fcolorbox{skyblue}{skyblue}{I \: think \: you \: want \: to \: know \: the \: magnitude}$

EXPLANATION :

$\star \: \bf {Given:}$

$\sf( - 2 \hat{i} - 3 \hat{j}) + 3 \hat{k}$

$\star \: \: \bf {Formula :}$

$\sf \overrightarrow{A} = x \hat{i} + y \hat{j} + z \hat{k} \\ \\ \implies \: \sf | \overrightarrow{A}| = \sqrt{ {x}^{2} + {y}^{2} + {z}^{2} }$

$\star \: \: \bf{Solution :}$

$\sf{Modulus \: of \: vector = \sqrt{ {(-2)}^{2} + {(-3)}^{2} + {(3)}^{2} } } \\ \\ \sf\implies {\boxed{ \boxed{ \mathfrak{\sqrt{22} }}}}$
