Can someone please help me with this.

Answer:

Step-by-step explanation:

Given expression is $|8-6 i|$ .

$|8-6 i|$ is a complex expression.

The value of i is –1.

By definition of absolute value, $|a+b i|=\sqrt{a^{2}+b^{2}}$

Now, substitute $|8-6 i|$ in the above formula.

$\Rightarrow|8-6 i|=\sqrt{8^{2}+(-6)^{2}}$ (since i = –1)

$=\sqrt{64+36}$ (since $8^{2}=64$ and $–6^{2}=36$ )

$=\sqrt{100}$ (Square root of 100 is 10)

= 10

Hence, the value of the expression $|8-6 i|$ is 10.

X^2 -9 divided by x+3

WINSTONCH [101]

Step-by-step explanation:

Hey, there!!

Given that,

$\frac{ {x}^{2} - 9 }{x + 3}$

{ we can write (a^2-4) as (a^2 - 2^2) also as (x^2- 9) can be written as (x^2 - 3^2)}.

$\frac{ {x}^{2} - {3}^{2} }{x + 3}$

We have a^2-b^2= (a+b) (a-b), so keep same formula on it.

$\frac{(x + 3)(x - 3)}{(x + 3)}$

(x+3) in numerator and denominator gets cancelled,

$(x - 3)$

Therefore, (x-3) is the final value.

Hope it helps...
