Question

d)
$\sqrt{a } + 3.5 = \sqrt[3]{ - 27} + ( - {2})^{2}$
​

Answer 1

$\sqrt{a} + 3,5 = \sqrt[3]{-27} + (-2)^{2} \\\\\sqrt{a} + 3,5 = \sqrt[3]{(-3)^{3} } + 4\\\\\sqrt{a} + 3,5 = -3 + 4\\\\\sqrt{a} + 3,5 = 1\\\\\sqrt{a} = 1 - 3,5\\\\\sqrt{a} = -2,5\\\\\\((\sqrt{a} )^{2} = (-2,5)^{2}\\\\\\ a = 6,25$
