Explanation of Solution

Inverse of the given matrix:

Consider the given matrix,

A=[1 0 11 1 12 1 2]

Suppose that the inverse of the given matrix is as follows:

A-1=[e f gh i jk l m]

Applying Gauss Jordan method,

Replacing row 2 by (row 2 – row 1), the following matrix is obtained,

[1 0 10 1 0

What are the two errors in my pseudocode?Module getAverage(Integer value1, Integer value2, Integer value3)                 Declare Integer average                 average = value1 + value2 + value3 / 3                 Display average            End Module
Where did I make an error in my pseudocode module???Code:Module main()                 Call raiseToPower(2, 1.5)            End main              Module raiseToPower(Real value, Integer power)                 Declare Real result                 Set result = value ^ power                 Display result            End raiseToPower
Why does my pseudocode not perform what I asked? Don't know whats wrong with it.// This program asks the user to enter a value             // between 1 and 10 and validates the input.             Declare Integer value                         // Get a value from the user.             Display "Enter a value between 1 and 10."             Input value               // Make sure the value is between 1 and 10.             While value < 1 AND value > 10                         Display "ERROR: The value must be between 1 and 10."                         Display "Enter a value between 1 and 10."                         Input value             End While
