**Knights**, Thursday, March 21, 2013 at 5:33pmI am assuming you mean log _10 x = 4 in the equation.

For this, log _x y = z, x^z = y

So, x = 10^4 = 10,000 (a)

(b) log _x 5 = 2, x^2 = 5, x = sqrt 5

(c) i guess you meant log 10_ 8 = x so 10^x = 8

plug this into calculator, "log 8" to get 0.903089987 etc...

good luck
