[tex] \bf \: a = 100 - ( {7}^{2} + {3}^{3} )[/tex]
[tex] \bf \: a = 100 - (49 + 27)[/tex]
[tex] \bf \: a = 100 - 76[/tex]
[tex] \boxed{\boxed{ \bf{a = 24}}}[/tex]
[tex] \bf \: b = 25 {}^{4} \div {5}^{8} [/tex]
[tex] \bf \: b = {5}^{2 \times 4} \div 5 {}^{8} [/tex]
[tex] \bf \: b = {5}^{8} \div {5}^{8} [/tex]
[tex] \boxed{ \boxed {\bf \: b = 1}}[/tex]
✏ [tex] \bf \pink{b {}^{a} = {1}^{24} = > \boxed{ \bf \: {b}^{a} = 1} }[/tex] ☑
