Question

what is the integral part of 5​

Answer 1

Answer:

5 is integral part of 5

Step-by-step explanation:

complex no. is written as

z= x+ i y

here x is integral part

y is imaginary part

Answer 2

Assuming that I denotes the integral part and f denotes the functional part of (5+2

)

n

. Then,

I+f=5

Considering 5−2

<1 and is also positive, therefore (5−2

n

is a proper fraction with out an integral part.

⋅6+……)=An even Integer

but since f and f

are proper integer their sum must be 1 for I+f+f

′

to be an integer.

Therefore I is an odd integer
