Question

qual o valor da expressão (4/5 + 3/2)² : (3/2 x 5/2) é?

Answer 1

$(\frac{4}{5}+\frac{3}{2} )^{2} : (\frac{3}{2}*\frac{5}{2} )\\\\(\frac{23}{10} )^{2}:\frac{15}{4}\\\\\frac{529}{100}:\frac{15}{4}=\frac{529}{100}*\frac{4}{15}=\frac{2116}{1500}=\frac{529}{375}=\boxed{1.41066666667}$

Espero que seja isso!
