Answer 1

Răspuns:

Explicație pas cu pas:

completeaza:

a) (5³)⁰=1

b) (2³)⁵=2³ˣ⁵=2¹⁵

c) (1³⁰)⁵⁰=1³⁰ˣ⁵⁰=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=1×(7²)¹⁵:7³⁰=1×7³⁰:7³⁰=1

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

g) (21³)⁵:(21²)7=21¹⁵:21¹⁴=21

h) (2³)⁵:(21²)7= asta cred ca l-ai gresit si ai scris din nou h dar ai uitat sa stergi ceea ce ai gresit.

h) (2³)⁵×(4³)⁵:(8³)⁴=​2¹⁵×4¹⁵:8¹²=2¹⁵×2³⁰:2³⁶=2⁴⁵:2³⁶=2⁽⁴⁵⁻³⁶⁾=2⁹
