Question

3 la puterea 1996 - 3 la puterea 1995 -3 la puterea 1994 -5 x 9 la puterea 1997

2 la puterea 1996 + 2 la puterea 1995 + 2 la puterea 1994 - 7 x 4 la puterea 1997

(7+11 la puterea 198 : 11 la puterea 196):64

3 la puterea 2 - 3 la puterea 2 : (2 la puterea 5 -2 la puterea 4 - 2 la puterea 3 -2 la putere 2 -2 la puterea 1 +2 la puterea 0)

Answer 1

3¹⁹⁹⁶ - 3¹⁹⁹⁵ -3¹⁹⁹⁴ -5 x 9¹⁹⁹⁷= 3¹⁹⁹⁴ *(3²-3-1)- 5*9¹⁹⁹⁷=3¹⁹⁹⁴*5- 5*9¹⁹⁹⁷=
=5*(3¹¹⁹⁴- 3³⁹⁹⁴)=5*3¹⁹⁹⁴*(1-3²⁰⁰⁰)
⁰⁰
2¹⁹⁹⁶ + 2¹⁹⁹⁵ + 2¹⁹⁹⁴ - 7 x 4¹⁹⁹⁷= 2¹⁹⁹⁴ *(2²+2+1) -7*4¹⁹⁹⁷=2¹⁹⁹⁴ *7 -7*4¹⁹⁹⁷=
=7*( 2¹⁹⁹⁴ - 2³⁹⁹⁴)= 7*2¹⁹⁹⁴*(1- 2²⁰⁰⁰)

(7+11¹⁹⁸ : 11¹⁹⁶):64= (7+11²) :64= 128:64=2

3² - 3² : (2⁵ -2⁴ - 2³ -2² -2¹ +2⁰)=3²-3²:(32-16-8-4-2+1)=3²-3²:3=9-3=6
