Question

Ma ajutati va rog?
a) ( 2 supra 3 )la puterea a 2 + 8 supra 15
b) (- 1 supra 2 ) la puterea a 3 * 16
c) (- 5 supra 6 ) la puterea a 2 * 1 intreg si 1 supra 5
d) ( 5 supra 9 - 3 supra 7 ) la puterea 0

Answer 1

a) (2 supra 3) la puterea a 2+8 supra 15=4 supra 9+8 supra 15=20 supra 45+24 supra 45=44 supra 45
b)(-1 supra 2) la puterea a 3*16= -1 supra 8* 16 supra 1= -2
c)(-5 supra 6) la puterea a 2*1 intreg si 1 supra 5= 25 supra 36*6 supra 5=5 supra 6.
d) (5 supra 9- 3 supra 7) la puterea 0= 1, fiindca orice numar la puterea 0=1.

Answer 2

$a) ( \frac{2}{3}) ^{2} + \frac{8}{15} = \frac{4}{9} + \frac{8}{15} = \frac{41}{45} ;$
$b) (\frac{-1}{2}) ^{3} *16= \frac{-1}{8} * \frac{16}{1} = \frac{-16}{8} =-2;$
$b) ( \frac{-5}{6}) ^{2} *1 \frac{1}{5} = \frac{25}{36} * \frac{6}{5} = \frac{5}{6} ;$
$d)( \frac{5}{9}- \frac{3}{7}) ^{0} = \frac{5}{9} - \frac{3}{7} = \frac{8}{63} .$
