Solve each of the following equations for x A 2x233 A Approx

Solve each of the following equations for x. A. 2^(x-2)=33

A._________________________ (Approximate to three decimal places for your final answer.)

B. 4 ln(x)-1=-19 B._________________________ (Give an exact answer using positive exponents.)

A. 2^(x-2)=33

taking natural log on both sides we get:

ln2^(x-2) = ln33

(x-2)ln2 = ln33

(x-2)ln2/ln2 = ln33/ln2

x -2 = 5.044

x = 7.044

B. equation is not clear
