Question

Oblicz.
a) 5⁴ + 5⁴ + 5⁴ + 5⁴ + 5⁴/53
b) 0,25⁴ * 28⁶/7⁶
c) 2⁶ * 5¹² * 7⁶/3,5⁶ : 10¹⁰​

Answer 1

Odpowiedź:

a) 5⁴ + 5⁴ + 5⁴ + 5⁴ + 5⁴/53= (5*5⁴)/53=5⁵/53=3125/53=58  51/53

b) 0,25⁴ * 28⁶/7⁶= 0,25⁴* 4⁶*7⁶/7⁶= (1/4)⁴*4⁶= 4⁻⁴*4⁶= 4²=16

c) 2⁶ * 5¹² * 7⁶/3,5⁶ : 10¹⁰​= (14⁶*5¹²)/3,5⁶:10¹⁰= [14⁶*(5²)⁶] / 3,5⁶:10¹⁰=

(14⁶*25⁶)/3,5⁶   :10¹⁰=350⁶/3,5⁶   : 10¹⁰= 100⁶: 10¹⁰= (10²)⁶:10¹⁰= 10¹²⁻¹⁰= 100
