Answer 1

Răspuns:

Explicație pas cu pas:

completeaza:

a) (5³)⁰= 1

b) (2³)⁵= 2¹⁵

c) (1³⁰)⁵⁰= 1¹⁵⁰⁰=1

d) (2⁵)³×(2³)⁵:(2³)¹⁰= 2¹⁵×2¹⁵:2³⁰=2³⁰:2³⁰=1

e) (7³⁰)⁰×(49⁵)³:(7⁶)⁵= 1×49¹⁵:7³⁰=(7²)¹⁵:7³⁰=7³⁰:7³⁰=1

f) (3¹)⁵:(9³)²= 3⁵:9⁶=3⁵:(3²)⁶=3⁵:3¹²=1:3⁷-Ai scris corect la f) ?

g) (21³)⁵:(21²)7= Probabil trebuia scris (21³)⁵:(21²)⁷=21¹⁵:21¹⁴=21

h) (2³)⁵:(21²)7= aici ai copiat gresit- nu am ce rezolva

h) (2³)⁵×(4³)⁵:(8³)⁴= 2¹⁵×4¹⁵:8¹²=2¹⁵×2³⁰:2³⁶=2⁴⁵:2³⁶=2⁹
