Question

help cu regulile puteri ​

Answer 1

Răspuns:

Explicație pas cu pas:

a) 2¹⁷ * 2²¹ = 2¹⁷⁺²¹ = 2³⁸

b) 3⁴⁷ * 3⁸⁷ * 3⁵⁵ = 3¹³⁴ * 3⁵⁵ = 3¹⁸⁹

c) 7¹⁹ * 7⁸³ * 7 = 7¹⁰² * 7 = 7¹⁰³

d) 2⁴⁷ : 2³⁹ = 2⁴⁷ ⁻ ³⁹ = 2⁸

e) 5¹⁰⁸ : 5⁷² = 5³⁶

f) 2³⁷ * 2⁴⁷ : 2⁵⁰ = 2⁸⁴ : 2⁵⁰ = 2³⁴

g) (10¹²)¹⁵ = 10¹⁸⁰

h) (2¹⁷)⁸ * 2³¹   = 2¹³⁶ * 2³¹ = 2¹⁶⁷

i)3¹⁰⁸ : (3¹⁵)⁶ = 3¹⁰⁸ : 3⁹⁰ = 3¹⁸

j) (3⁷ * 5¹²)² = (15¹⁹)² = 15³⁸

k) (2¹⁰ * 3⁷)⁹ : (2⁵ * 3⁶)¹⁰=

= (6¹⁷)⁹ : (6¹¹)¹⁰=

= 6¹⁵³ : 6¹¹⁰=

= 6⁴³
