Failure to display the formula correctly

[saraOrkide]

ex mml code :

<math display='inline'> <mo>(</mo> <mn>4</mn> <mo>)</mo> <mi> </mi> <mi> </mi> <mfenced open='{' close='' separators='|'> <mrow> <mtable> <mtr> <mtd> <mi>A</mi> <mi>B</mi> <mo>=</mo> <mi>A</mi> <mtext>'</mtext> <mi>B</mi> <mtext>'</mtext> <mo>=</mo> <mi>c</mi> </mtd> <mtd /> </mtr> <mtr> <mtd> <mi>A</mi> <mi>C</mi> <mo>=</mo> <mi>A</mi> <mtext>'</mtext> <mi>C</mi> <mtext>'</mtext> <mo>=</mo> <mi>b</mi> </mtd> <mtd /> </mtr> <mtr> <mtd> <mi>B</mi> <mi>C</mi> <mo>=</mo> <mi>B</mi> <mtext>'</mtext> <mi>C</mi> <mtext>'</mtext> <mo>=</mo> <mi>a</mi> </mtd> <mtd /> </mtr> <mtr> <mtd /> <mtd /> </mtr> </mtable> </mrow> </mfenced> <mi> </mi> <mi> </mi> <mover accent='false'> <mo>→</mo> <mrow> <mtext>ض ض ض</mtext> </mrow> </mover> <mover> <mrow> <mi>A</mi> <mi>B</mi> <mi>C</mi> </mrow> <mrow> <mtext>Δ</mtext> </mrow> </mover> <mi> </mi> <mo>≅</mo> <mover> <mrow> <mi>A</mi> <mtext>'</mtext> <mi>B</mi> <mtext>'</mtext> <mi>C</mi> <mtext>'</mtext> </mrow> <mrow> <mtext>Δ</mtext> </mrow> </mover> <mi> </mi> <mo>⇒</mo> <mtable columnalign='left'> <mtr> <mtd> <mtable columnalign='left'> <mtr> <mtd /> <mtd> <mover accent='true'> <mrow> <mi>B</mi> </mrow> <mo>^</mo> </mover> <mo>=</mo> <mover accent='true'> <mrow> <mi>B</mi> <mtext>'</mtext> </mrow> <mo>^</mo> </mover> </mtd> </mtr> <mtr> <mtd /> <mtd> <mover accent='true'> <mrow> <mi>C</mi> </mrow> <mo>^</mo> </mover> <mo>=</mo> <mover accent='true'> <mrow> <mi>C</mi> <mtext>'</mtext> </mrow> <mo>^</mo> </mover> </mtd> </mtr> <mtr> <mtd /> <mtd> <mover accent='true'> <mrow> <mi>A</mi> </mrow> <mo>^</mo> </mover> <mo>=</mo> <mover accent='true'> <mrow> <mi>A</mi> <mtext>'</mtext> </mrow> <mo>^</mo> </mover> <mo>=</mo> <mn>9</mn> <msup> <mrow> <mn>0</mn> </mrow> <mrow> <mo>∘</mo> </mrow> </msup> <mo>⇒</mo> <mover accent='true'> <mrow> <mi>A</mi> </mrow> <mo>^</mo> </mover> <mo>=</mo> <mn>9</mn> <msup> <mrow> <mn>0</mn> </mrow> <mrow> <mo>∘</mo> </mrow> </msup> </mtd> </mtr> <mtr> <mtd /> <mtd /> </mtr> </mtable> </mtd> </mtr> <mtr> <mtd /> </mtr> </mtable> </math>

The bracket placed for the number 4 is too big using version of mathjax 2.7.9

This is the correct rendering of the MathML you have given. It is also a duplicate of your #3141, which reports the same "issue". The solution there is the solution here as well: use an <mrow> around the <mo>(</mo> <mn>4</mn> <mo>)</mo>, as recommended by the MathML specification.
