Classroom Rules. Absolutely no talking (unless it’s about math) Stay in your seat at all times No bathroom (except for emergencies). Solving Equation. x 2 = 16 x = √1̅6̅ = 4 Because 4∙4 = 16 x = -√1̅6̅ = -4 Because (-4)∙(-4) = 16. x 2 = 15 x = √1̅5̅ Because √1̅5̅ ∙ √1̅5̅ = 15

Classroom Rules • Absolutely no talking (unless it’s about math) • Stay in your seat at all times • No bathroom (except for emergencies)
Solving Equation x2 = 16 x = √1̅6̅ = 4 Because 4∙4 = 16 x = -√1̅6̅ = -4 Because (-4)∙(-4) = 16 x2 = 15 x = √1̅5̅ Because √1̅5̅ ∙ √1̅5̅ = 15 x = -√1̅5̅ Because (-√1̅5̅) ∙ (-√1̅5̅) = 15
Try it together x2 = 5 x3 = 5
