Question

9x ×5x =14580
Find the value of x

Answer 1

Answer:

18

Step-by-step explanation:

$9x \times 5x = 14580$

$45 {x}^{2} = 14580$

${x}^{2} = 14580 \div 45$

${x}^{2} = 324$

$x = \sqrt{324}$

$x = 18$

Answer 2

Answer:

Step-by-step explanation:

9x × 5x = 14580

45x² = 14580

x² = 14580 ÷ 45

x² = 324

x = ± √324

$x_{12}$ = ± 18

$x_{1}$ = - 18,

$x_{2}$ = 18
