Question

cat face 125^42 : 25^63 urgenttt​ (dau coroana)

Answer 1

125^42 : 25^63 = 5^126 : 5^126 = 1

125 = 5^3

125^42= (5^3)^42 = 5^126

25^63 = (5^2)^63 = 5^126

Answer 2

125⁴²=(5³)⁴²=5³ˣ⁴²=5¹²⁶

25⁶³=(5²)⁶³=5²ˣ⁶³=5¹²⁶

5¹²⁶:5¹²⁶=1

sau

5¹²⁶:5¹²⁶=5¹²⁶⁻¹²⁶=5⁰=1

a⁰=1

a¹=a

aⁿ*aᵇ=aⁿ⁺ᵇ

aⁿ:aᵇ=aⁿ⁻ᵇ

(aⁿ)ᵇ=aⁿˣᵇ
