Penjelasan dengan langkah-langkah:
[tex]{□}^{ \frac{●}{☆} } - (● - ☆) = \frac{4}{2} \sqrt{8} + 1[/tex]
Jika • = x , ★ = y
[tex] {32}^{ \frac{x}{y} } - (x - y) = \frac{4}{2} \sqrt{8} + 1 \\ \\ {32}^{ \frac{x}{y} } - (x - y) = 4 \sqrt{2} + 1 \\ \\ ( {32}^{ \frac{x}{y} }) - ( x - y) = (\sqrt{32}) + 1 \\ \\ {32}^{ \frac{x}{y} } = \sqrt{32} \\ {32}^{ \frac{x}{y} } = {32}^{ \frac{1}{2} } \\ \\ maka \: x = 1 \: dan \: y = 2 \\ uji \\ - (x - y) = 1 \\ - (1 - 2) = 1 \\ - 1 + 2 = 1 \\ 1 = 1 \: terbukti[/tex]
Maka ★ = 2 dan • = 1
