Let x = log84 Use the principle that the log equationis equivalent to the exponential equation 8x = 4 Write 8 as 23 and 4 as 22 (23)x = 22 Remove the parentheses on the left by multiplying the exponent inside the parentheses, 3, by the exponent outside the parentheses x 23x = 22 Now we use the principle that if and B is positive and not equal to 1, then 3x = 2 2 x = ——— 3 Edwin
