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: 
First bring all terms in 'a' to the left side of the formula by subtracting ac from both sides
ab - ac - cd = ac - ac
ab - ac - cd = 0
now add cd to both sides
ab - ac -cd + cd = cd
ab - ac = cd
now factor the left side by taking out the 'a'
a(b-c) = cd
now divide both sides by (b-c)
a = cd / (b-c)
done
Answer:10 and 20
Step-by-step explanation:Shreyas age:X
Arjuns age: 2x
Shreyas age 5 years ago:x-5
Arjuns age 5 years ago: 2x-5
We get the equation: 2x-5=3(x-5)
2x-5=3x-15
2x-3x=-15+5
-x=-10
X= 10
Shreyas present age is 10 years
Arjuns present age is 2x(2×10) =20 years
