Question

Efectuati :
a:) (2x2x3)x{2x2^2x2^43-2^46+[3^148:3^43-(3^5)^21]+16}=
b) 122+12x{183:[(2x3^2x5^3)^4:(2^4x3^7x5^12)+(2^8)^9:2^72-1^27x5^0]-9x(54-2^4x3)}

Answer 1

A) (2×2×3)×{2^(1+2+43)-2^46+[3^(148-43)-3^(5×21)]+16}

=12×[2^46-2^46+(3^105-3^105)+16]

=12×(0+0+16)=12×16=194

Answer 2

a)  ( 2 x 2 x 3 ) x { 2 x 2 x 2⁴³ - 2⁴⁶ + [ 3¹⁴⁸ : 3⁴³ - ( 3⁵ ) ²¹ ] + 16 } = 192

= 12 x { 2 ⁽ ¹ ⁺ ² ⁺ ⁴³ ⁾ - 2⁴⁶  + [ 3 ⁽ ¹⁴⁸ ⁻ ⁴³ ⁾ - 3⁵ ˣ ²¹ ] + 16 } =

= 12 x [ 2⁴⁶ - 2⁴⁶ + ( 3 ¹⁰⁴ - 3¹⁰⁵ ) + 16 ]=

= 12 x ( 0 + 0  + 16 )=

= 12 x 16 =

= 192

b)

122 + 12 x { 183 : [ ( 2 x 3² x 5³ ) ⁴ : ( 2⁴ x 3⁷ x 5¹² ) + ( 2⁸ )⁹ : 2⁷² - 1²⁷ x 5⁰ ] - 9 x ( 54 - 2⁴ x 3 ) } =

= 122 + 12 x { 183 : [ ( 2⁴x 3⁸ x 5¹²)  : ( 2⁴ x 3⁷ x 5¹² ) + 2 ⁽ ⁸ˣ ⁹ ⁻⁷² ⁾ - 1 x 1 ] - 9 x ( 54 - 16 x 3 ) } =

= 122 + 12 x [ 183 : ( 3 + 2⁰ - 1 ) - 9 x ( 54 - 48 ) ] =

= 122 +12 x ( 183 : 3 - 9 x 6) =

= 122 + 12 x ( 61 - 54 ) =

= 122 + 12 x 7 =

= 122 + 84 =

= 206
