mohon bantuannya beserta caranya
[tex]4 \sqrt{7} - (2 \sqrt{7} - 3 \sqrt{7} )[/tex]
​

Penjelasan dengan langkah-langkah:

[tex] = 4 \sqrt{7} - (2 \sqrt{7} - 3 \sqrt{7} )[/tex]

[tex] = 4 \sqrt{7} - ((2 - 3) \sqrt{7} )[/tex]

[tex] = 4 \sqrt{7} - ( - 1) \sqrt{7} [/tex]

[tex] = 4 \sqrt{7} + 1\sqrt{7} [/tex]

[tex] = (4 + 1) \sqrt{7} [/tex]

[tex] = 5 \sqrt{7} [/tex]
