Question

[4 supra 3 ×(4 supra 3)⁵]⁷ ÷(4 supra 3)⁴⁰ -(5 supra 6)²​

Answer 1

Răspuns:

Explicație pas cu pas:

[4/3 ×(4/3)⁵]⁷ = [(4/3)^6]^7 = (4/3)^42

(4/3)^42 : (4/3)^40 = (4/3)^2 = 16/9

16/9 - (5/6)^2 = 16/9 - 25/36 = 64/36 - 25/36 = 39/36 = 13/12

Answer 2

Răspuns 39/36

Explicație pas cu pas:

=[(4/3) ^ 6] ^ 7 :(4/3)^40-(5/6)^2

=(4/3)^42:(4/3)^40-(5/6)^2

= (4/3)^2 -( 5/6)^2

=39/36 =13/12
