Potrzbne na dzisiaj do 21:30 :)
Oczywiscie chce obliczenia i odpowiedzi :) :
a)5 do potęgi 5 kreska ułamkowa 10 do 4
b)44 do 4 kreska ulamkowa 22 do 3
c) 64 do 2 * 36 do 2 kreska ulamkowa 6 do 3 * 2do 7
d)4 do 6 * 8 do 6 kreska ulamkowa 32 do 5
e)(-3)do 9 * 5 do 7 kreska ulamkowa 15 do 8
f) 2 do 8 * 5 do 7 kreska ulamkowa 0,1 do 4 * 100 do 6
To wrzystko czekam do 21 : 30 :)

a)najpierw piec piatych rozpisujesz na cale liczby i 10 do potegi 4 =
525
= 0,0525
10000
b)
a)5 do potęgi 5 kreska ułamkowa 10 do 4
= 5⁵ / (5⁴ *2⁴)=
=( 5⁵ : 5⁴)*(1/2)⁴=
= 5*(1/2)⁴=
= 5*(1/16) =
= 5/16
b)44 do 4 kreska ulamkowa 22 do 3=
=44⁴/ 22³=
= (2*22)⁴/ 22³=
= 2⁴*22⁴/ 22³=
= 2⁴* 22¹ =
= 16*22 =
= 352
c) 64 do 2 * 36 do 2 kreska ulamkowa 6 do 3 * 2do 7 =
= 64² * 36² / 6³*2⁷=
= (2⁶)²* (6²)²/ 6³*2⁷=
= (2¹²* 6⁴) : (6³*2⁷)=
= (2¹²:2⁷)*(6⁴: 6³) =
= 2⁵* 6¹=
= 2⁵*2*3 =
= 3*2⁶=
= 3*64=
= 192
d)4 do 6 * 8 do 6 kreska ulamkowa 32 do 5=
= (2²)⁶* (2³)⁶/ (2⁵)⁵=
= 2¹²* 2¹⁸/ 2²⁵=
= 2²⁷: 2²⁵=
= 2² =
= 4
e)(-3)do 9 * 5 do 7 kreska ulamkowa 15 do 8=
= (-3)⁹*5⁷/ (3 *5)⁸=
= (-3)⁹*5⁷/ (3⁸ *5⁸)=
= [(-3)⁹: 3⁸]*[ 5⁷:5⁸] =
= -(3)¹ * 5⁻¹ =
= - 3 * 1/5 =
= - 3/5
f) 2 do 8 * 5 do 7 kreska ulamkowa 0,1 do 4 * 100 do 6=
= (2⁸*5⁷) / (1/10)⁴*(10²)⁶=
= (2*2⁷*5⁷) / [ 10⁻⁴*10¹²] =
= 2*(2*5)⁷ : [ 10⁸] =
= 2* 10⁷ : 10⁸=
= 2*10⁻¹=
= 2*(1/10) =
= 2/10 =
= 1/5
