Question

Aflați X din: {5×[(2^9×30^101)^3:(2^303×15^303)+X-(2^3)^9]}÷2=25​

Answer 1

Răspuns:

Explicație pas cu pas:

{5×[(2^9×30^101)^3:(2^303×15^303)+X-(2^3)^9]}÷2=25​  

5×[(2^9×30^101)^3:(2^303×15^303)+X-(2^3)^9]} = 25×2

{5×[(2^9×30^101)^3:(2^303×15^303)+X-(2^3)^9]} = 50

(2^9×30^101)^3:(2^303×15^303)+X-(2^3)^9 = 50 : 5

(2^9×30^101)^3:(2^303×15^303)+X-(2^3)^9 = 10

2^27 x 30^303 : 2^303 x 15^303 + X - 2^27 = 10

2^27 x 30^303 : 30^303 + X - 2^27 = 10

2^27 x 1 + X - 2^27 = 10

2^27 + X - 2^27 = 10

x = 10

Answer 2

{5 × [(2⁹ × 30¹⁰¹)³: (2³⁰³× 15³⁰³) + x - (2³)⁹]} : 2 = 25​

5 × [2²⁷ × 30³⁰³ : (2 × 15)³⁰³ + x - 2²⁷] = 50

2²⁷ × 30³⁰³ : 30³⁰³ + x - 2²⁷ = 10

2²⁷ + x - 2²⁷ = 10

x = 10
