Question

15/31÷90/186×729/9=x2

Answer 1

Answer:

The value of $x$ is $\pm 9.$

Step-by-step explanation:

The given equation is $\frac {15}{31}\div \frac {90}{186}\times \frac {729}{9}=x^2$

Find the value of $x.$

Solution:

According to the question

So, $\frac {15}{31}\div \frac {90}{186} \times \frac {729}{9}=x^2$

$= \frac{15}{31} \times \frac {186}{90} \times \frac {729}{9}=x^2$

$=81=x^2$

$x=\pm \sqrt{81}$

$x=\pm 9$

Hence, the value of $x$ is $\pm 9.$
