log_{7}(x^2)=2

lo g_{7} (x^{2}) = 2

x = 7, x = - 7

Solution steps

lo g_{7} (x^{2}) = 2

Apply log rules

x^{2} = 49

Solve

x^{2} = 49 : x = 7, x = - 7

x = 7, x = - 7

0.678 = ln (x^{2})

2 lo g_{2} (x + 5) - lo g_{2} (x + 9) = 1

x, ln (y) = 2 ln (x)

ln (x) + ln (x + 1) = ln (12)

lo g_{3} (x) = - \frac{2}{3}
