Question

sa se rez ecuatia : 3 la puterea 2-x = 1 supra 9

Answer 1

$3^{2} - x = \frac{1}{9}$

$9 - x = \frac{1}{9}$

$x = \frac{1}{9} + \frac{1}{1}$

$x = \frac{1}{9} + \frac{9}{9}$

$x = \frac{18}{9}$

$Am ~ amplificat~ pe~ \frac{1}{9} ~ cu ~ 1 ~ si ~ pe~ \frac{1}{1} ~ cu ~ 9$

Answer 2

3²-x=1/9
9-x=0,(1)
x=9-0,(1)
x=8,(8)9
