Question

Exerciţiile 1 și 2. Va rog din suflet.
Dau coroniţă.. Mulţumesc mult.! :)

Answer 1

1). a) 32
b)0.0081
c)2,25
d)0,343
e)$\frac{2 ^{4} }{ 9^{4} }$
f) $\frac{32}{243}$
g)1 deoarece orice numar la puterea 0 este 1
h)$\frac{1 ^{9} }{9 ^{9} }$
i)$\frac{ 23^{2} }{ 99^{2} }$
j)$\frac{ 15^{3} }{ 90^{3} }$

2)a) 0,2²+0,3²-0,13=
=0,04+0,09-0,13
=0,13-0,13=0

b)nu stiu

Answer 2

2 la puterea 5 =32
0.3 la puterea 4 =0.0081
1.5² =2.25
0.7³ =0.343
0.(2) la puterea 4 =(2/9) la puterea 4 =16/6561
(2/3)^5=32/243
(11/14)^0 =1
(1/9)^3=1/729
0.(23)^2=(23/99)^2=529/9801
[0.1(6)]^3=(16/96)^3=4096/884736
ex 2: 
0.2^2+0.3^2-0.13=0.04+0.09-0.13=0
[0.(1)^2+0.(2)^2+0.(2)^2] / 0.(1)=[(1/9)^2+(2/9)^2+(2/9)^2]/(1/9)=
(1/81+4/81+4/81)/(1/9)=(9/81)/1/9=(1/9)/(1/9)=1
