Question

The students of a school participated in a
drill. There were 2^x-1rows of students and
in each row there were 2^x+3 students. If
1024 students took part in the drill, find
the number of rows of the students?​

Answer 1

Answer:

8 rows

Step-by-step explanation:

$2^{x-1}$ × $2^{x+3}$ = 1024

$2^{x - 1 +x+3}$ = $2^{10}$

2x + 2 = 10 ⇒ x = 4

$2^{4-1}$ = 2³ = 8 rows
