Answer 1

Oie, Td Bom?!

>>> Resolvendo a expressão numérica.

$[ \right - ( \frac{1}{5} ) {}^{ - 2} + 9 {}^{ \frac{1}{2} } + 0.001 {}^{0} ] \right - 8 {}^{ \frac{1}{3} }$

$[ \right - 5 {}^{2} + ( 3 {}^{2} ) {}^{ \frac{1}{2} } + 1 ] \right - (2 {}^{3} ) {}^{ \frac{1}{3} }$

$[ \right- 25 + 3 + 1 ] \right - 2$

$[ \right - 21 ] \right - 2$

$- 21 - 2$

$- 23$
