Answer:

10

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)


=√(64+36) (since
8^(2)=64 and
–6^(2)=36)


=√(100) (Square root of 100 is 10)

= 10

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