Question

qual é o valor de y=(-5)²- 4²+(3/5)/3-²+1

Answer 1

Resposta:

$=400\frac{14}{15}$

Explicação passo a passo:

$\left(-5\right)^2\left(-4\right)^2+\left(\frac{3}{5}\right)-\frac{2}{3}+1$

$=25\left(-4\right)^2+\left(\frac{3}{5}\right)-\frac{2}{3}+1$

$=25\cdot \:16+\left(\frac{3}{5}\right)-\frac{2}{3}+1$

$=400+\left(\frac{3}{5}\right)-\frac{2}{3}+1$

$=\frac{6014}{15}$

$=400\frac{14}{15}$
