Wolfram Alpha reports that the biological half-life of Iodine-131 is 138 days, and half-life, in the biological sense, is the time it would take for the substance involved to be decayed in half by natural processes. WebAnswer (1 of 13): Let us work on this equation, 2x = 138 We need the value of x So, * 2x = 138 * x = 138/2 * x = 69 Therefore, x is 69 The value of x is 69 x = 69 So, the equation implies that the value of x is 69 and therefore the equation is, 2x = 138 i.e. (2× 69) = 138 Because, 138...
