Question

calcule a expressão 0,2 ^
1 -3 √1/1000 + 57/1000 1/2

Answer 1

Resposta:

0,2255

Explicação passo a passo:

$0,2^1-3\cdot \frac{\sqrt{1}}{1000}+\frac{57}{1000}\cdot \frac{1}{2}$

$=0,2^1-3\cdot \frac{1}{1000}+\frac{1}{2}\cdot \frac{57}{1000}$

$=0,2-3\cdot \frac{1}{1000}+\frac{1}{2}\cdot \frac{57}{1000}$

$=0,2-\frac{3}{1000}+\frac{57}{2000}$

$=-\frac{6}{2000}+\frac{57}{2000}$

$=\frac{-6+57}{2000}$

$=0,2+\frac{51}{2000}$

$=0,2+0,0255$

$=0,2255$
