Answer:

5

Explanation:

Answer: 5

Explanation:

For any complex number z= a+ib , where a and b are arbitrary real numbers.

The modulus of z is |z|=\sqrt{a^2+b^2}∣z∣=a2+b2

Let z=4-3iz=4−3i , here a=4 and b= -3

Then, |z|=|4-3i|=\sqrt{4^2+(-3)^2}∣z∣=∣4−3i∣=42+(−3)2

=\sqrt{16+9}=\sqrt{25}=5=16+9=25=5

Hence, the xpression that is equivalent to |4-3i| is 5.
