The square root of -48 is 2 because 2x2x2x2x2x2x is not -48
Answer:
6
Step-by-step explanation:
xy=k
Value of k ; when ; x = - 3 and y = - 2
Put x = - 3 and y = - 2 into the equation :
(-3)(-2) = k
-3 * - 2 = k
6 = k
The constant of variation k = 6
Answer:
Step-by-step explanation:
Given the expression:
To find:
The expression of above complex number in standard form 
.
Solution:
First of all, learn the concept of 
(pronounced as <em>iota</em>) which is used to represent the complex numbers. Especially the imaginary part of the complex number is represented by .
Value of 
.
Now, let us consider the given expression:
So, the given expression in standard form is .
Let us compare with standard form so we get 
.
The standard form of
is: 
For this case, the first thing we must do is define a variable.
We have then:
x: real number
Now we write the expression:
-8 / (x + 3)
The number x can be all real different from minus three.
Answer:
-8 / (x + 3)
With x different from -3.
Answer:
5/3
Step-by-step explanation:
35 and 21 could be divided by a factor of 7.
35 ÷ 7 = 5
21 ÷ 7 = 3
So,
35/21 = 5/3
