Triangularizing matrix gives the matrix that has only zeroes above or below the main diagonal. To find which option is correct we need to calculate all of them.
In all these options we calculate result and write it into row that is first mentioned:

Answer:
☪ First , Let's know about Exponential Equation :
⤿ Let's take an equation : .
In this equation , the variable ' x ' is the exponent of the base 2. Such an equation in which variable appears as an exponent of a base is known as exponential equation. The following axioms are useful while solving the exponential equations :
- If
, then
- If
, then
and x = 0
---------------------------------------------------------------
☯ Now , Let's Solve :
In this equation , the variable 'x' is the exponent of the base 8 .Write in exponential form with the base of 2
↦
Write the number 2 in exponential form with the base of 2.
↦
Since the bases are same , cut 2 on both sides and set the exponents equal.
↦
↦
Divide both sides by 3
↦
↦
And we're done!
Hope I helped!
Have a wonderful day! ツ
