Question 924460


The modulus must be a positive number.
If the complex number {{{Z = jb}}}, {{{mod(Z) = sqrt( (jb)^2)}}}, where {{{mod(Z)}}} denotes the modulus of {{{Z}}}.


{{{mod(Z)=sqrt( (-1i)^2)}}}

{{{mod(Z)=sqrt( 1i^2)}}}

{{{mod(Z)=sqrt( i^2)}}}

{{{mod(Z)=i}}}


since {{{ sqrt( (jb)^2)}}} is {{{abs(b)j)}}}, then you can find {{{mod(Z)}}} this way:

{{{mod(Z)=abs(-1)i}}}

{{{mod(Z)=1i}}}

{{{mod(Z)=i}}}
