Question

ex 1 , 2...va rog !! am nevoie de el urgent

Answer 1

1

a) 6⁴-5² = 1296-25 = 1271

b)471-0=471

c)(3² x 2)² = (9x2)²= 18² =324

d)(2+2²+2³): (10¹ - 3) = (2+4+8): 7=14:7=2

2

2x{2 x 2² x 2³ + 3³ : 3⁰ + 23 x [5⁴:5³+2¹⁰⁰ x (8+2³)- (2⁴)²⁶]}

2x [2⁴+ 3³+23x ( 5² +2¹⁰⁰ x 2⁴ - 2¹⁰⁴)]

2x (16 + 27 + 23 x 5²)

2x (16+27+ 23x25)

2x (16 + 27+ 575)

2x 618 =1236

Sper ca te-am ajutat ! ;)

O zi frumoasa

Answer 2

1 )

a) 6⁴ - 5² = 1 296 - 25 = 1 271

b) 477¹ - 0²⁰¹² = 477 - 0 = 477

c) ( 3² x 2 )² = ( 9 x 2 )² = 18² = 324

d) ( 2 + 2² + 2³ ) : ( 10¹ - 3 ) = ( 2 + 4 + 8 ) : 7 = 14 : 7 = 2

2 x { 2 x 2² x 2³ + 3³ : 3⁰ + 23 x [ 5⁴ : 5³ + 2¹⁰⁰ x ( 8 + 2³ ) - ( 2⁴ )²⁶ ] } =

= 2 x { 2 ⁽ ¹⁺²⁺³ ⁾ + 3³ + 23 x [ 5 ⁽ ⁴⁻³ ⁾ + 2¹⁰⁰ x ( 8 + 8 ) - 2 ⁴ˣ²⁶ ] } =

= 2 x [ 2⁶ + 27 + 23 x ( 5 + 2¹⁰⁰ x 2⁴ - 2¹⁰⁴ ) ] =

= 2 x [ 64 + 27 + 23 x ( 5 + 2¹⁰⁴ - 2¹⁰⁴ ) ] =

= 2 x [ 91 + 23 x ( 5 + 0 ) ]=

= 2 x ( 91 + 23 x 5 ) =

= 2 x ( 91 + 115 ) =

= 2 x 206 =

= 412
