Evaluate :
$\sqrt{- 25} + 3 \sqrt{- 4} + 2 \sqrt{- 9}$

$5 i$
$6 i$
$17 i$
$- 17 i$

$\sqrt{- 25} + 3 \sqrt{- 4} + 2 \sqrt{- 9}$

$= 5 \sqrt{- 1} + 6 \sqrt{- 1} + 6 \sqrt{- 1}$ we know, $\sqrt{- 1} = i$

$= 5 i + 6 i + 6 i = 17 i$

Evaluate : √−25+3√−4+2√−95i6i17i−17i

√−25+3√−4+2√−9=5√−1+6√−1+6√−1 we know, √−1=i=5i+6i+6i=17i

Evaluate :
$\sqrt{- 25} + 3 \sqrt{- 4} + 2 \sqrt{- 9}$

$5 i$
$6 i$
$17 i$
$- 17 i$

$\sqrt{- 25} + 3 \sqrt{- 4} + 2 \sqrt{- 9}$

$= 5 \sqrt{- 1} + 6 \sqrt{- 1} + 6 \sqrt{- 1}$ we know, $\sqrt{- 1} = i$

$= 5 i + 6 i + 6 i = 17 i$
