Question

What is x to the 2nd power=1/49

Answer 1

Let's begin by identifying key information given to us:

`\begin{gathered} x^2=(1)/(49) \\ \text{Take the square root of both sides, we have:} \\ \sqrt[]{x^2}=\sqrt[]{(1)/(49)}\Rightarrow x=\sqrt[]{(1^2)/(7^2)} \\ \Rightarrow x=\pm(1)/(7) \\ \\ \therefore x=\pm(1)/(7) \end{gathered}`
