log_{2}(x)log_{2}(x)=9

lo g_{2} (x) lo g_{2} (x) = 9

x = 8, x = \frac{1}{8}

Decimal Notation

x = 8, x = 0.125

Solution steps

lo g_{2} (x) lo g_{2} (x) = 9

Rewrite the equation with

lo g_{2} (x) = u

uu = 9

Solve

uu = 9 : u = 9, u = - 9

u = 9, u = - 9

Substitute back

u = lo g_{2} (x),

solve for

x

Solve

lo g_{2} (x) = 9 : x = 8

Solve

lo g_{2} (x) = - 9 : x = \frac{1}{8}

x = 8, x = \frac{1}{8}

Verify Solutions:

x = 8

True

, x = \frac{1}{8}

True

The solutions are

x = 8, x = \frac{1}{8}

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

0.789 = ln (x^{2})

0.42 = ln (x)

ln (y) = x^{2}, y

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