z= √(r^2+Xl^2).
=√(100^2+100^2).
=√20000).
= 141.4.
=√(100^2+100^2).
=√20000).
= 141.4.

Z =√(r^2*+l^2).
=√(100*100+100*100).
=√(20000).
=141.4.
=√(100*100+100*100).
=√(20000).
=141.4.

z = sqrt(r squared +XL squared),
Substituting values,we have;
z = sqrt(20000),
z = 141.4ohms.
Substituting values,we have;
z = sqrt(20000),
z = 141.4ohms.

Another way to express this is due to Resistor and Inductance current flow are not in the same phase they can be shown as below. Total impedance cannot be plus but use trigonometric equation,
Z^2 = Xl^2 R^2.
Z = sqr(Xl^2 R^2).
Z = sqr(100 * 100 + 100 * 100) = sqr(20000) = 141.4 ohms.
Z^2 = Xl^2 R^2.
Z = sqr(Xl^2 R^2).
Z = sqr(100 * 100 + 100 * 100) = sqr(20000) = 141.4 ohms.

R = 100 XL = 100.
Z = sqr(100*100+100*100) = sqr(20000) = 141.4 ohms.
Z = sqr(100*100+100*100) = sqr(20000) = 141.4 ohms.

Z = R+jXL.
Then convert it into polar form.
Then convert it into polar form.

z=sqrt(R^2+X^2),then z=sqrt(100^2+100^2)
therefore z=sqrt(20000) so implies sqrt(10000*2)
100sqrt(2) i.e100*1.414=141.4
therefore z=sqrt(20000) so implies sqrt(10000*2)
100sqrt(2) i.e100*1.414=141.4

If Z=sqrt(R^2+X^2), then Z=sqrt(100^2+100^2)
Therefore, Z=200. Right?
Therefore, Z=200. Right?
