|z|=a2+b2
therefore,the magnitude or modulus of the complex number 5i is:
we can write the complex number as 0+5i
therefore the magnitude or modulus of the complex number is 02+52=52=5
therefore the magnitude or modulus of complex number 5i is 5
the magnitude or modulus of the complex number 7 is:
we can write the complex number as 7+0i
therefore the magnitude or modulus of the complex number is 72+02=72=7
therefore the magnitude or modulus of complex number 7 is 7
the magnitude or modulus of the complex number 3+4i is:
therefore the magnitude or modulus of the complex number is 32+42=9+16=25=5
therefore the magnitude or modulus of complex 3+4i is 5.
