penjelasan eksponen kelas 10​

Let the original number of seats in a row be x; Let the number rows be y;
( x + 3) * (y - 2 )= 72 and x * y = 72 => 72 + 3 * y - 2 * x = 72 => 3 * y = 2 * x; => x is divisible by 3;

x = 3 => y = 72 / 3 => y = 24;
x = 6 => y = 72 / 6 => y = 12;
x = 9 => y = 72 / 9 => y = 8;
x = 12 => y = 72 / 12 =. y = 6;
x = 24 =. y = 72 / 24 => y = 3;
x = 36 => y = 72 / 36 => y = 2;
x = 72 => y = 72 / 72 => y = 1;

My analysis tell me that the right answer is 9 seats in a row and 8 rows; The original number in each row is 9.

The original number of seats in each row is 9. There were originally 8 rows. This arrangement totals 72 seats in the classroom.

Jawaban:Eksponen adalah cara singkat menulis perkalian berulang suatu bilangan. Ditulis sebagai a^n, di mana: * a adalah basis (bilangan yang dikalikan). * n adalah pangkat (berapa kali a dikalikan).Contoh: 2³ = 2 ×2 × 2 = 8.
