Question

if 3^2x=1, then find the value of x​

Answer 1

Answer:

3x^2 -1 =0

a = 3 c = -1 and b = 0

Using the quadratic formula:

x = [-b +- sqr root (b^2 - 4ac)] / 2a

x = [-0 +- sqr root (0^2 - 4*3 *-1] / -2 * 3

x = +- sqr root (12) / -6

x = +2 * sqr root (3)  /-6

x1 = + sqr root (3)  / -3

x2 = -sqr root (3) / -3
