Question

Calculati: 3^90-4x9^44+2^208x(2x4^1003)-5x(9^22)^2= (URGENT)

Answer 1

Răspuns:

2^2215

Explicație pas cu pas:

3^90 - 4*[(3^2)^44]+ 2^208(2*2^2006) -5*[3^(44)]^2 =

3^90 - 4*3^88 + 2^208*2^2007 -5 * 3^88=

3^88( 3^2 - 4 -5) + 2^208+2^2007=

3^88* 0 + 2^2215= 2^2215

Answer 2

3^90 - 4 × 9^44 + 2^208 × (2 × 4^1003) - 5 × (9^22)^2 =

= 3^90 - 4 × (3^2)^44 + 2^208 × [2 × (2^2)^1003] - 5 × 9^44 =

= 3^90 - 4 × 3^88 + 2^208 × (2 × 2^2006) - 5 × (3^2)^44 =

= 3^90 - 4 × 3^88 + 2^208 × 2^2007 - 5 × 3^88 =

= 3^90 - 4 × 3^88 - 5 × 3^88 + 2^2215 =

= 3^88 × (3^2 - 4 - 5) + 2^2215 =

= 3^88 × 0 + 2^2215 =

= 2^2215
