log_{2}(81)=4log_{2}(x)

lo g_{2} (81) = 4 lo g_{2} (x)

x = 3

Solution steps

lo g_{2} (81) = 4 lo g_{2} (x)

Switch sides

4 lo g_{2} (x) = lo g_{2} (81)

Divide both sides by

4

lo g_{2} (x) = \frac{lo g _{2} ( 81 )}{4}

Apply log rules

x = 3

Verify Solutions:

x = 3

True

The solution is

x = 3

ln (x) = 588.4

4 = 2 lo g_{5} (\frac{W - 1}{100})

10 lo g_{10} (y) = - 0.423

1.432 = 4.72 - 2.5 lo g_{10} (x)

lo g_{10} (x) = - 3.8
