BECAUSE OF THE MAGNITUDE OF THE EXPONENTS (-8 TO +54) ONE REALLY NEEDS A SCIENTIFIC CALCULATOR. HAVING NONE YOU CAN:
3.5*4.4=15.4*10^(-8-4)=15.4*10(-12)
15.4*10(-12)/2.43*10^45
6.337*10(-12)/10^45)
6.337*10(-12-45)
6.337*10^-57
--------------------------------------------------------------
(3.5*10^-8)(4.4*10^-4)/(2.43*10^45)
(1.54*10^-11)/2.43*10^45 SORRY I MESSED UP THE LAST STEP. I HAD THE POWER=54 INSTEAD OF 45.
6.337*10^-57 ANSWER.
