Question

Mim Ajudem Pfvr isso é pra segunda ​

Answer 1

$(2^2)^1 +3^3 - 7^2\\4 + 27 - 49\\31 - 49\\-18$

$\sqrt{25} + 8^2 - \sqrt{100} \\5 + 64 - 10\\69 - 10\\59$

$\sqrt{x} + 2 = 5\\\sqrt{x} = 5 -2\\\sqrt{x} = 3\\x = 3^2\\x = 9$

$\sqrt[3]{x+5} = 3\\x+5 = 3^3\\x+5 = 27\\x = 27 -5\\x = 22$

$\sqrt{a} - \sqrt{b} - (\sqrt{a} * \sqrt{b} )\\\sqrt{49} - \sqrt{16} - (\sqrt{49} * \sqrt{16} )\\7 - 4 - (7 * 4 )\\3 - ( 28 )\\-25$

$\frac{a}{\sqrt{a} } * \frac{b}{\sqrt{b} } \\\frac{49}{\sqrt{49} } * \frac{16}{\sqrt{16} } \\\frac{49}{7 } * \frac{16}{4 } \\7 * 4\\28$
