Question

 

x = 76 - [ 26 + ( 16 - 2 . 7)^3 ]

 

 

Answer 1

x = 76 - [26 +(16-14)³]

x= 76 - [26+8]

x= 76-34

x=42

Answer 2

\(x=76-\left[26+\left(16-2\times7\right)^3\right]\)

  \(=76-\left[26+\left(2\right)^3\right]\)

  \(=76-\left[26+8\right]\)

  \(=76-34\)

  \(=42\)

Answer 3

\(x=76-\left[26+\left(16-2.7\right)^3\right]\)

\(76-\left[26+\left(16-2.7\right)^3\right]=x\)

\(76-\left[26+\left(-670\right)\right]=x\)

\(76-\left(-644\right)=x\)

\(\Rightarrow x=720\)

Answer 4

\(x=76-\left[26+\left(16-2\times7\right)^3\right].\)

\(=76-\left[26+\left(16-14\right)^3\right]\)

\(=76-\left[26+2^3\right]\)

\(=76-\left[26+8\right]\)

\(=76-34\)

\(=42\)
