Answer 1

Răspuns

Ex 4)A3= 302400, B = 8

Ex 5) a >b

Calculează

A)

3024 × 58 + 3024 × 43 - 3024 =

3024 × ( 58 + 43 - 1) =

3024 × 100 =

302400

B)

[ 8 + 8 × ( 8 ^2 + 8 ^98 : 8 ^96)] : 129 =

[ 8 + 8 × ( 8 ^2 + 8^2)] : 129 =

[ 8 + 8 ×( 64 + 64)] : 129 =

( 8 + 8 × 128) : 129 =

( 8 + 1024) : 129 =

1032 : 129 =

8

Compară numerele

a= ( 3 ^2) ^3 × 3 ^4 × 3 ^4

a = 3 ^( 2 × 3) × 3 ^4 × 3 ^4

a = 3 ^6 ×3 ^4 × 3 ^ 4

a = 3 ^( 6 + 4 + 4)

a = 3 ^14

b = 27 = 3 ^3

a > b
