Check each true statement about the number 7- square root 3i

kumpel [21]

Answer:

option-A

option-D

Step-by-step explanation:

We are given a complex number as

$7-\sqrt{3}i$

we know that whenever we have

$a+bi$

where

a is the real number

b is imaginary number

now, we can verify each statement

option-A:

we can see that

a=7

and

a is the real number

so, 7 will be real number

so, this is TRUE

option-B:

we know that

$b=-\sqrt{3}$

so, imaginary number is $-\sqrt{3}$

while it is mentioned square root 3 is the imaginary part of the number

so, this is FALSE

option-C:

We can see that coefficient of i is b

and

$b=-\sqrt{3}$

so, this is FALSE

option-D:

we know that

'a' and 'b' are sum of real and imaginary number

so, this is TRUE
