$(- 7 \cdot \sqrt{675} i - \sqrt{675} j + 25 \cdot \sqrt{675} k)$ $(-7*sqrt 675i-sqrt 675j+25*sqrt 675k)$

Explanation:

$step 1: find the magnitude of the vector a=(-7i-j+25k)$ $"step 1: find the magnitude of the vector a=(-7i-j+25k")$
$| | v | | = \sqrt{{(- 7)}^{2} + {(- 1)}^{2} + 25^{2}}$ $||v||=sqrt ((-7)^2+(-1)^2+25^2)$
$| | v | | = \sqrt{49 + 1 + 625} = \sqrt{675}$ $||v||=sqrt(49+1+625)=sqrt 675$
$s t e p 2 :$ $step 2:$
$\sqrt{675} \cdot \to a$ $sqrt 675* vec a$
$\sqrt{675} (- 7 i - j + 25 k)$ $sqrt 675(-7i-j+25k)$
$(- 7 \cdot \sqrt{675} i - \sqrt{675} j + 25 \cdot \sqrt{675} k)$ $(-7*sqrt 675i-sqrt 675j+25*sqrt 675k)$
