Question

what is the absoulte vaule of 12-2i

Answer 1

\[12 + 2i\]

Answer 2

2(6+i)

Answer 3

Red'bone: it's not the absolute value that you are looking for, but the "magnitude". And, for "a+bi", the magnitude is |a+bi| = sqrt( a^2 + b^2 )

Answer 4

caveman has it, solve it,and post ur answer,we'll check if its rite :)

Answer 5

the answwer was wrong

Answer 6

ok the answer is sqrt(12^2+(-2)^2)=sqrt(148)=12.17.
concept of magnitude of a complex number is, wen u hav a+ib then in the argand plane(a plane like x-y,where x represents real values and y represents imaginary values) its just a point (a,b).by magnitude , u mean the length of the linesegment joining (a,b) to (0,0). so use distance formula to find it :)

Answer 7

get it?
