Answer 1

a) -(3/2)² = 9/4 = 2¼

b)3²+(-3)³=9 + (-27)= -18

c) (-2)³ + 2² = -8 + 4 = -4

d)4*3³/2 do 4 = 4*27/16 = 108/16 = 6.75

e)(-⅔)³ = (-8/27)

f)(-⅛)³ - 3² = (-⅛) - 9 = (-⅛) - 9/1 = (-⅛) - 72/8 = -73/8 = -9⅛  ⅛ - jedna ósma

g)(-2)do 4 / 3² = 16/9 =  1 i 7/9

h)½³ - (⅓)² = ⅛ - 1/9 = 9/72 - 8/72 = 1/72

i)(-3)³ / 2³ = -27/8 = -3 i 3/8

j)(-10)² * (-0.1)³ = 100 * (-0.001) = (-0.1)

k)(-½)² + (-½)² + (-2½)² = ¼ + ¼ + 4¼ = 4¾

l) 3 * 2² + 5 * (-3)³ = 3 * 4 + 5 * (-27) = 12 + (-135) = -123

m) 2do 5 - (3²-2³) = 2do 5 - (9-8) = 32 - 1 = 31

n) (3² * 3do15) / (3do 7 * 3do 8) = 3do 17 / 3do 15 = 3² = 9

o) (2do 7 /2³) / (2 * 2² * 2³) = 2do 4 / 2do 6 = 2 do -2 czyli (-2)² = ¼

p) 7 * 7³ / (7²)² / 7³ / 7² * 7 = (7do4 / 7do4) / (7³ / 7³) = 1

r)(3½)² / 3½ / (3½)³ / 3½ = 3½ / (3½)² = (3½) do -1 czyli (-3½)

s) 4 * 2² + 9 * (-3)³ = 4 * 4 + 9 * (-27) = 16 + (-243) = (-227)

t) a² * a * b³ * b do5 * b² = a³ * b do10

u)x do4 * x do9 y² * x * y do4 x² = x do5 * x do10 y do6

w) a² * b³ * b do4 * (-a) * a do4 = a do5 * b do7

z) a³ * b² * c * a * b³ * a * bdo4 * c³ = a do5 * b do9 * c do4

ż) a³ * a do5 / a² = a do8 / a² = a do6

a') x do5 / x² / x * x³ = x² * x³ = x do5

b') a do8 / a / (a²)³ / a do5 = a do7 / a do6  / a do5 = a do7 / a = a do6

c') (x² * x do5)³ / (x³ * x do4)² / (x²)³ = (x do7)³ / (x do12)² / x do6 = x do-3 / x do-6 = x do-9

d')[(ab)³]do4 / [(ab)³]³ = ab do12 / ab do9 = ab³

 

Liczę na naj bo się baaardzo naprwacowałam ;)
