Question

o valor da expressão〖32〗^0,2+〖27〗^0,5 -((108)_2^1)/2+〖(0,0016)〗^0,25 é : obs o 108 e elevado a 1/2

Answer 1

$32^{0.2}+27^{0.5}\:-\:(\frac{108^{\frac{1}{2}}}{2})+0.0016^{^{0.25}} = \\\\ = 32^{0.2}+27^{\frac{1}{2}}-\frac{108^{\frac{1}{2}}}{2}+0.0016^{0.25}\\\\ = 32^{0.2}+3\cdot \:3^{\frac{1}{2}}-3\cdot \:3^{\frac{1}{2}}+0.0016^{0.25}\\\\\\ como\;\;3\cdot \:3^{\frac{1}{2}}-3\cdot \:3^{\frac{1}{2}}=0\\\\\\ = 32^{0.2}+0.0016^{0.25}\\\\ = 2+0.0016^{0.25}\\\\ = 2+0.2\\\\ = \framebox{ 2.2 }$
