hmm..so you're asking for the absolute value of (7-3i).. right? the absolute value of a complex number is also called the modulus of that complex number. Say you have a+bi. the modulus is |a+bi| = sqrt(a^2 + b^2).
Similarly, given |7-3i|, modulus = sqrt(7^2 + 3^2)= sqrt(49+9)
=sqrt(58). this is the answer
i hope its clear enough, good day!:D

abs(7-3i) is square root of 7^2+(-3)^2 that is square root of 49+9 and finally we get square root of 58.

maybe you mean modulus = sqrt( 7^2+3^2) = sqrt(58)
