Lorico [155]

Answer:

Javier flew his kite for 4 more hours on Wednesday and Thursday than Monday and Tuesday.

Step-by-step explanation:

He flew his kite for 4 hours on Wednesday and 3 hours on Thursday.

4 + 3 = 7.

Previously, on Monday, he flew his kite for 1 hour, and on Tuesday, he flew his kite for 2 hours.

1 + 2 = 3.

7 - 3 = 4.

Simplify the expression fraction with numerator of the square root of negative four and denominator of the quantity three plus i

Alex787 [66]

Answer:

$\frac{-4+2i}{5}$

Step-by-step explanation:

We are given the expression, $\frac{\sqrt{-4}}{(3+i)-(2+3i)}$

On simplifying, we have,

$\frac{2i}{3+i-2-3i}$

i.e. $\frac{2i}{1-2i}$

Now, we will rationalize the expression,

i.e. $\frac{2i}{1-2i}\times \frac{1+2i}{1+2i}$

i.e. $\frac{(2i)\times (1+2i)}{(1-2i)\times (1+2i)}$

i.e. $\frac{2i+4i^{2}}{1-4i^{2}}$

Since, $i^{2}=-1$ , we get,

i.e. $\frac{2i-4}{1+4}$

i.e. $\frac{-4+2i}{5}$

So, the simplified expression is $\frac{-4+2i}{5}$ .
