Question

Calcule o valor de (-2)⁴ :4²-4²:(-2)⁵

Answer 1

$= ( - 2) {}^{4} \div 4 {}^{2} - 4 {}^{2} \div ( - 2) {}^{5}$

$= 2 {}^{4} \div 2 {}^{4} - 4 {}^{2} \div ( - 2 {}^{5} )$

$= 1 + 2 {}^{4} \div 2 {}^{5}$

$= 1 + 2 { }^{ - 1}$

$= 1 + \frac{1}{2}$

$= \frac{2 + 1}{2}$

$\boxed{ = \frac{3}{2} }$
