Question

a)(3⁷)⁶×3²:3⁴¹-5²
b)(2⁷)⁸×2²:2⁵⁰-4²
c)(5⁷)⁵×5³:5³⁵-5³
d)(9+3¹⁰⁰:3⁹⁸+3⁴⁵:3⁴³):3³
e)144³:12⁵-12⁵:(2²×3)⁴+3×3²:3³​

Answer 1

a) (3⁷)⁶×3²:3⁴¹-5²=3⁴²×3²:3⁴¹-5²=3⁴⁴:3⁴¹-5²=3³-5²=27-25=2

b) (2⁷)⁸×2²:2⁵⁰-4²=2⁵⁶×2²:2⁵⁰-4²=2⁵⁸:2⁵⁰-4²=2⁸-4²=256-16=240

c)(5⁷)⁵×5³:5³⁵-5³=5³⁵×5³:5³⁵-5³=5³⁸:5³⁵-5³=5³-5³=0

d) (9+3¹⁰⁰:3⁹⁸+3⁴⁵:3⁴³):3³=(3²+3²+3²):3³=(9+9+9):27=27:27=1

e) 144³:12⁵-12⁵:(2²×3)⁴+3×3²:3³=(12²)³:12⁵-12⁵:12⁴+3³:3³=12⁶:12⁵-12+1=12-12+1=1
