What is 5/12 × 6/35

please evaluate!

Step-by-step explanation:

You can do this without cancelation to start with.

5*6 / 12 * 35 = 30 / 420 = 1/14  

However you can cancel twice.

first cancel 5 into 35 that gives 7 where the 35 was

6 / (7 * 12)

Now you can cancel 6 into 12

1 / (7 *2)

1/14

Same answer.

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
