#7) i believe its using the equation N = No*e(decay constant)t. (decay constant = the upside down y, just cant type it). if you dont think its this equation, but a diff one, that's okay, just thought it might be useful. thank you so so much, its due tomorrow morning and im confused and want to learn how to do these. thank you!! :)

7. Calculate the decay constant () of 152Gd from its half-life of 1.11014 ? Please show all work and units. (10 points)
