19=0.074t^4

19 = 0.074 t^{4}

Solution steps

19 = 0.074 t^{4}

Switch sides

0.074 t^{4} = 19

Multiply both sides by

1000

74 t^{4} = 19000

Divide both sides by

74

t^{4} = \frac{9500}{37}

Rewrite the equation with

u = t^{2}

and

u^{2} = t^{4}

u^{2} = \frac{9500}{37}

Solve

u^{2} = \frac{9500}{37} : u = \frac{9500}{37}, u = - \frac{9500}{37}

u = \frac{9500}{37}, u = - \frac{9500}{37}

Substitute back

u = t^{2},

solve for

t

Solve

t^{2} = - \frac{9500}{37} : t = - \frac{10 95}{37}, t = - - \frac{10 95}{37}

The solutions are

4 x^{4} - 5 x^{2} = - 4

x^{3} + x - 7 = 0

x^{4} + x^{2} + 2 x + 6 = 0

b (2) = x^{3} + 3

y^{4} - 4 y^{3} + 6 y^{2} - 4 y^{1} + y = 0
