Find the two pairs of numbers whose LCM is the product of the numbers

help pls

3 and 5

7 and 2

4 and 3

Step-by-step explanation:

3×5=15 and its LCM is also 15

7×2=14 and its LCM is also 14

4×3=12 and its LCM is also 12

step-by-step explanation:

the original amount doesn't ''re just looking for the time it takes for 1/2 of the substance to we have

(1/2) =)     take the ln   of both sides

ln (1/2)   = )   and we can write

ln(1/2) = ) lne     and lne   = 1     so we have

ln(1/2) = -.1092t     divide both sides by -.1092

t = ln(1/2)/-.1092 = about 6.347 days = about 6.3 days (rounded)
