Question

2^5+12(x^3-20)=116

Answer 1

Ta có : 2 ^ 5 + 12 . ( x ^ 3 - 20 ) = 116

=> 32 + 12 . ( x ^ 3 - 20 ) = 116

=> 12 . ( x ^ 3 - 20 ) = 116 - 32

=> 12 . ( x ^ 3 - 20 ) = 84

=> x ^ 3 - 20  = 84 : 12

=> x ^ 3 - 20  = 7

=> x ^ 3 = 7 + 20

=> x ^ 3 = 27

=> x ^ 3 = 3 ^ 3

=> x = 3 

Vậy x = 3

Answer 2

\(2^5+12\left(x^3-20\right)=116\)

\(\Rightarrow32+12\left(x^3-20\right)=116\)

\(\Rightarrow12\left(x^3-20\right)=116-32=84\)

\(\Rightarrow x^3-20=84:12=7\)

\(\Rightarrow x^3=7+20=27\)

\(\Rightarrow x^3=3^3\Rightarrow x=3\)

Vậy \(x=3\)

Answer 4

\(2^5+12\left(x^3-20\right)=116\)

\(32+12x^3-12\cdot20=116\)

\(32+12x^3-240=116\)

\(32+12x^3=116+240\)

\(32+12x^3=356\)

\(12x^3=356-32\)

\(12x^3=324\)

\(x^3=324\div12\)

\(x^3=27\)

Mà \(3^3=27\)

\(\Rightarrow x=3\)

Answer 5

2⁵ + 12(x³ - 20) = 116

32 + 12(x³ - 20) = 116

12(x³ - 20) = 116 - 32

12(x³ - 20) = 84

x³ - 20 = 84 : 12

x³ - 20 = 7

x³ = 7 + 20

x³ = 27

x³ = 3³

=> x = 3

Answer 6

\(2^5+12\left(x^3-20\right)=116\)

\(32+12\left(x^3-20\right)=116\)

\(12\left(x^3-20\right)=116-32\)

\(12\left(x^3-20\right)=84\)

\(\left(x^3-20\right)=84\text{ : }12\)

\(x^3-20=7\)

\(x^3=7+20\)

\(x^3=27\)

\(x^3=3^3\)

\(x=3\)
