Question

Calculati:16 la puterea 502 - 8 la puterea 669 - 4 la puterea 1003 va rog URGENT!!!

Answer 1

$16^{502} - 8^{669}- 4^{1003} = (2^{4}) ^{502} - (2^{3}) ^{669} - (2^{2})^{1003} =$$2^{2008} - 2^{2007} - 2^{2006}$
Si de aici nu mai stiu.

Answer 2

16⁵⁰² -8⁶⁶⁹ -4 ¹⁰⁰³ =
(2⁴) ⁵⁰² -(2 ³ )⁶⁶⁹ - (2 ²) ¹⁰⁰³
=2 ²⁰⁰⁸ -2²⁰⁰⁷ -2 ²⁰⁰⁶
=2²°°⁶ * ( 2²- 2 -1) 
= 2²⁰⁰⁶* (4-2-1)
=2²⁰⁰⁶ *1
= 2 ²⁰⁰⁶
