Question..

Answer 1

Modulus of \[i^3(1+i) \] is

Answer 2

Is it 2 ?

Answer 3

first multiply it..
i^2 = -1
after simplifying.. apply the formula of modulus.

Answer 4

What is the formula ?

Answer 5

By the way it is i^3

Answer 6

Ok So 1+i^3

Answer 7

u can split i^3 in i^2.i

Answer 8

I have solved it now tell me how can i take modulus ?

Answer 9

1+i^2.i
i^2=-1
1-i
general form =a+ib
formula of modulus =(a^2+b^2)^0.5

Answer 10

Where did you get the power from ? i.e 0.5

Answer 11

its the formula.. its basically square root. \[\sqrt{a ^{2}+b ^{2}}\]

Answer 12

ok thanks :)

Answer 13

you are welcome. :)
