ln(sqrt(x+7))=4

ln (x + 7) = 4

x = e^{8} - 7

Solution steps

ln (x + 7) = 4

Apply log rules

x + 7 = e^{4}

Solve

x + 7 = e^{4} : x = e^{8} - 7

x = e^{8} - 7

lo g_{9} (x) + lo g_{9} (x - 8) = 1

2 ln (x) = - 1

lo g_{x} (x + 30) = 2

lo g_{7} (x) = 1.69

ln (x + 15) - ln (3 - 2 x) = 4 ln (2)
