c) 3² *3³= 3⁵=243
2⁵⁴ : 2⁵²= 2²=4
(3⁵)⁴=3²⁰
(3⁵)⁴: 3²⁰=1
=> [243+4+1]:31= 248:31=8
e) 576=24²
24²:576=24²:24²=1
(3²*2)¹⁵:(3²⁹*2¹⁵)=(3²)¹⁵:3²⁹*2¹⁵:2¹⁵=3³⁰:3²⁹*1=3*1=3
1²¹=1
=> 10*{1+3*[3+1]}:13=10*(1+12):13=10*13:13=10
f) 2⁵⁰*2⁴⁸+(2¹⁰*2¹⁵)⁵:2²⁷= (2⁵⁰*2⁴⁸)+(2⁵⁰*2⁷⁵):2²⁷=2⁵⁰(2⁴⁸+2⁴⁸)=2⁵⁰*2⁴⁹
(5⁷⁶:5⁷⁵-3)⁹⁰*2⁸=(5-3)⁹⁰*2⁸=2⁹⁰*2⁸=2⁹⁸
=> 2¹⁰⁰:(2⁵⁰*2⁴⁹+2⁹⁸+2⁹⁸)=2¹⁰⁰:2⁵⁰*2⁴⁹+2¹⁰⁰:2⁹⁹=2⁵⁰*2⁴⁹+2
