Question

Calcular R=cos²60°×tg²45°×sen²30°

Answer 1

Respuesta:

$\frac{1}{16}$

Explicación paso a paso:

$(\frac{1}{2} )^{2} \times 1 {}^{2} \times ( \frac{1}{2} )^{2}$

$( \frac{1}{4} ) \times 1 \times ( \frac{1}{4} )$

$\frac{1}{16}$

Answer 2

Respuesta:

$R=\frac{1}{16}$

Explicación paso a paso:

$R=(\frac{1}{2}) ^{2} (\frac{1}{1})^{2} (\frac{1}{2} )^{2} \\R =(\frac{1}{2}.\frac{1}{1} .\frac{1}{2} )^{2} \\R=(\frac{1}{4} )^{2} \\R=\frac{1}{16}$
