Question

Select the correct answer what is the value of x in the equation 25 x 2 equals 16

Answer 1

25x2 = 16

=>

`\begin{gathered} 25x^2\text{ = 16} \\ \text{Divide both sides by 25} \\ (25x^2)/(25)\text{ =}(16)/(25) \\ \end{gathered}`

`\begin{gathered} x^2\text{ =}(16)/(25) \\ x\text{ =}\sqrt[]{(16)/(25)} \\ x\text{ =}\pm\text{ }(4)/(5) \end{gathered}`
