Question

VA ROG DIN SUFLET SA MA AJUTAȚI. AM NEVOIE URGENTA (dau corona + 80 de puncte ​

Answer 1

1.

a) = 3

b) = -8

c) = 9

d) = 12

2.

a) =3·0-5 = -5

b) = 2²-8 = 4-8 = -4

c) 5·(-1)³+2·(-1)²-4·(-1) = -5+2+4 = 1

d) = 7·(+∞)-3 = +∞

e) = (-9)·(-∞)-3 = +∞

f) = -(-∞)² = -∞

g) = +∞

h)= -(-∞)³= +∞

3.

a) = √9 = 3

b) = $\sqrt[5]{32} = \sqrt[5]{2^{5} }=2$

c) = (-∞)^(1/3) = -∞

d) = $\sqrt[4]{81} = \sqrt[4]{3^{4} } = 3$

4.

a) (1/2)²=1/4

b) +∞

c) +∞

d) 2³=8

e) = $(1/5)^{-inf} = (5)^{+inf} = +inf$

f) = 7^(-∞)= 1/$7^{inf}$ = 0

g) = 1/$3^{inf}$ = 0

h) 9^(1/2) = √9 = 3

5.

a) =+∞

b) $=log_{2} (2^{2} ) =2$

c) =-1

d) =-∞

e) = ln(e²) =2

f) -∞

g) =2

h) =3
