Question

5,și 6,dau coroana!!!

Answer 1

Răspuns:

exercițiu 6

X = 10² - ( 5² + 3² )

X = 100 - ( 25 + 9 )

X = 100 - 34

X = 66

y = 9⁴ : 3⁸

y = (3²)⁴ : 3⁸

y = 3⁸ : 3⁸

y = 3⁰

y = 1

X la puterea y = 66¹ = 66

exercițiu 5

(8⁴: 4⁵ + 27³ : 9⁴ + 2¹² : 2¹¹ ) : 3² = 1

[(2³)⁴ : (2²)⁵ + (3³)³ : (3²)⁴ + 2¹) : 9 =

( 2¹² : 2¹⁰ + 3⁹ : 3⁸ + 2 ) : 9 =

( 2² + 3¹ + 2 ) : 9 =

( 4 + 3 + 2 ) : 9 =

9 : 9 = 1
