Question

Calcule o valor de : (0,2) elevado a 2 + (0,16) elevado a 2

Answer 1

$(0,2)^2+(0,16)^2=$


$( \frac{1}{5} )^2 + ( \frac{4}{25} )^2$


$\frac{1}{25} + \frac{16}{625}$

$\frac{41}{625} = 0,06$

Answer 2

$\sf \left(0,\:2\right)^3+\left(0,\:16\right)^2\\\\\\\sf 0.2^3=0.008\\\\\\\sf =0.008+0.16^2\\\\\\\sf 0.16^2=0.0256\\\\\\\sf =0.008+0.0256\\\\\\\sf 0.008+0.0256=0.0336\\\\\\\sf \to \boxed{\sf =0.0336}$
