Question

(3la p 2-2 la p3)la p2*(8la p 5:4la p 7)la puterea 2=

Answer 1

( 3^2 - 2^3 ) ^2 * ( 8^5 : 4^7 ) ^ 2 = ( 9 - 8 ) ^ 2 * [ (2^3)^5 : (2^2)^7 ] ^ 2 = 1^2 * ( 2^15 : 2^14 ) ^ 2 = 1 * 2^2 = 1 * 4 = 4 .

Answer 2

(3^2 - 2^3)^2 × (8^5 :4^7)^2 =

= (9 - 8)^2 × 8^10 : 4^14 =

= 1^2 × (2^3)^10 : (2^2)^14 =

= 1 × 2^30 : 2^28 =

= 2^2 =

= 4
