Answer 2

Penjelasan dengan langkah-langkah:

[tex]9 \times 9 \times \text{y} = 27 \times 27 \times 27[/tex]

[tex] {3}^{2} \times {3}^{2} \times \text{y} = {3}^{3} \times {3}^{3} \times {3}^{3} [/tex]

[tex] {3}^{2 + 2} \times \text{y} = {3}^{3 + 3 + 3} [/tex]

[tex] {3}^{4} \times \text{y} = {3}^{9} [/tex]

[tex] \text{y} = \frac{ {3}^{9} }{ {3}^{4} } [/tex]

[tex] \text{y} = {3}^{5} [/tex]

[tex] \bold{y = 243}[/tex]
