f)(-4)-³?​

Answer 1

$\sf{\left(-\dfrac{3}{4}\right)}^{4}$

$\sf{\left(-\dfrac{3}{4}\right)}^{4} = \left(-\dfrac{3}{4}\right) \times \left(-\dfrac{3}{4}\right) \times \left(-\dfrac{3}{4}\right) \times \left(-\dfrac{3}{4}\right)$

$\sf{\left(-\dfrac{3}{4}\right)}^{4} = \dfrac{9}{16} \times \dfrac{9}{16}$

$\sf{\left(-\dfrac{3}{4}\right)}^{4} = \dfrac{81}{256}$
