• Problem:
What is the value of x in the given √x = 9 ?
• Solution:
✓To get the value of the square root of x, you need to multiply the expression by itself.
✓Since the problem is an equation, what you do on the either side of the equation, you'll do the same on the other side.
[tex] \tt( \sqrt{x} ) {}^{2} = 9 {}^{2} [/tex]
[tex] \tt{\sqrt{x•x}} = 81 \:\tt or \: \tt \cancel{(\sqrt{x} )} \cancel{{}^{2} } = 81[/tex]
[tex] \tt x = 81[/tex]
• Answer:
✓The value of x is 81.
