Answer:

$\sqrt{-5}=i\sqrt{5}$

$\sqrt{-25}=5i$

Step-by-step explanation:

i is an imaginary unit, this means

$i^2=-1$

Rewrite -5 as $5\cdot (-1)=5\cdot i^2,$

then

$\sqrt{-5}=\sqrt{5i^2}=\sqrt{5}\cdot \sqrt{i^2}=\sqrt{5}\cdot i=i\sqrt{5}$

Rewrite -25 as $-25=25\cdot (-1)=25\cdot i^2,$

then

$\sqrt{-25}=\sqrt{25\cdot i^2}=\sqrt{25}\cdot \sqrt{i^2}=5\cdot i=5i$

Answer:

Step-by-step explanation:

50 dollars = ∉34

∉1 = Rs 150

Rs 382800 / 150 Rs per ∉ = 382800/150 ∉

=2552 ∉

50 dollars = ∉34 so 50/34 dollars = ∉

2552 ∉ × 50/34 dollar per ∉ = in the units the ∉ cancel out

∉ × dollar/∉ = dollars

(2552 × 50) / 34 = 3752.94 dollars <------------------

Here is another way of looking at the answer...........

Rs 382800 × 1∉/150 Rs × 50 dollars/34 ∉ = note how the units cancel

= 382800 × (1/150) × (50/34) Rs × ∉/Rs × dollars/∉

= 3,752.94 dollars leaving only dollars in the numerator
