log_{7}(81)=4log_{7}(x)

lo g_{7} (81) = 4 lo g_{7} (x)

x = 3

Solution steps

lo g_{7} (81) = 4 lo g_{7} (x)

Switch sides

4 lo g_{7} (x) = lo g_{7} (81)

Divide both sides by

4

lo g_{7} (x) = \frac{lo g _{7} ( 81 )}{4}

Apply log rules

x = 3

Verify Solutions:

x = 3

True

The solution is

x = 3

lo g_{x} (\frac{1}{3}) = 10

0.78 = ln (y)

lo g_{7} (8) = 3 lo g_{7} (x)

x, t = lo g_{10} (x)

lo g_{2} (lo g_{2} (x)) = 0
