150º :
(7/9)²:

Answer 1

 Fazemos os cálculos:

$\red{\boxed{\orange{\boxed{\begin{array}{l}\bf Qualquer\:base\;elavada\:a\;um,ela\:se\\ \:\bf repetir\acute{a}.\end{array}}}}}$

$\red{\boxed{\orange{\boxed{\begin{array}{rcl}\\&{\sf 25^{1}=25}&\\\\\end{array}}}}}$

$\red{\boxed{\orange{\boxed{\begin{array}{l}\bf Qualquer\:base\;elavada\:a\;zero,\\ \bf sempre\:ser\acute{a}\:1. \end{array}}}}}$

$\red{\boxed{\orange{\boxed{\begin{array}{rcl}\\&{\sf 150^{0}=1}&\\\\\end{array}}}}}$

$\red{\boxed{\green{\boxed{\begin{array}{l}\sf como\:a\:frac_{\!\!,}\tilde{a}o\:est\acute{a}\:elevada\:a \\ \sf 2,repetimos\:duas\:vezes.\end{array}}}}}$

$\red{\boxed{\orange{\boxed{\begin{array}{rcl}\\&{\sf \Bigg({\dfrac{7}{9}\Bigg)^{2}=\dfrac{7}{9}\times\dfrac{7}{9}=\dfrac{49}{81}}}&\\\\\end{array}}}}}$
