Answer:
2
Step-by-step explanation:
Using the rule of logarithms
x = n ⇒ x = 
let
8 = n ⇒ 8 = 
, that is
2³ = ( equate exponents )
n = 3
and let
( 
) = n ⇒ = 
, that is
= ( equate exponents )
n = - 1
then
8 + ( )
= 3 + (- 1)
= 3 - 1
= 2
Hello from MrBillDoesMath!
Answer: 2
Description. Create a line from point A perpendicular to the x axis. This line, with the radius (OA) , and x axis, form a right triangle. By Pythagoras,
x-length y-length hypotenuse squared
( 3 ^ (1/2) ) ^ 2 + 1 ^ 2 = 3 + 1 = 4
So, the square of the hypotenuse (or radius OA in this case) is 4. That means OA is the square root of 4 or 2.

Firstly we must know what complex Number is .
Complex number - The number in the form of a + bi ,where a is real part and bi is Imaginary part is called a complex number . Also here value of i ( read as iota ) is √-1 . It can't be represented on the number line and is represented on the Argand Plane .
So , here the complex number given to us is 7 + 9i .
So , it can be written as ,
= 7 + 9i .
= 7 + 9√-1 .
= 7 + √9 × √9 × √-1 .
= 7 + √ 81 × -1 .
= 7 + √-81 .
