Find the gcf of 44j5k4 and 121j2k6. find the gcf of 44 and 121. find the gcf of j5 and j2. find the gcf of k4 and k6. what is the gcf of 44j5k4 and 121j2k6? 4j3k2 4j2k4 11j3k2 11j2k4 (this is the correct one)

x =-.20752

step-by-step explanation:

4^(x+2)=12

4^(x+2)=12

take the log base 4 on each side

log 4 (4^(x+2) = log 4(12)

we know log b(a^y) = y log b (a)

(x+2) log 4(4) = log 4 (12)

x+2 = log 4 (12)

we know   logb c = loga c/loga b

we want to convert to base 10   so a = 10

by default, we do not write the 10   c = 4   and b = 10

log4 10 = log 12/log 4

log4 10 = log 12/ log 4

x+2 = log 12/ log 4

subtract 2 from each side

x +2 -2 = log 12/ log 4 -2

x = 1.79248125 -2

x =-.20752
