Question

simplify the following :{(3)^-3 -5^3}÷6^0 ​

Answer 1

$\: \: \: \: \: \: \frac{ (( {3}^{ - 3} ) - ( {5}^{ 3} ))}{ {6}^{0} } \\ = \frac{ (( {3}^{ - 3} ) - ( {5}^{ 3} ))}{1} \\ = \frac{1}{ {3}^{3} } - (125) \\ = \frac{1}{27} - 125 \\ = \frac{1 - 3375}{27} \\ = \frac{ - 3374}{27 } \\ = - 124.96$
