Find the equation of tangent plane to z=3x2−xyz=3x2−xy at point (1,2,1)(1,2,1) a.
3x−y−z=−13x−y−z=−1

b.
4x−y+z=14x−y+z=1

c.
4x+y−z=14x+y−z=1

d.
4x−y−z=1

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
