Presentation transcript:

A square root radical is in simplest form when the radicand has no _______________. square factors 32 The radicand is the number inside he radical symbol Square factors are: 4, 9, 16, 25, 36, 49,… 22 32 42 52 62 72

= = = Look for the biggest squares that are factors: 4 is a factor of 32, but 16 is bigger = Write them as separate radicals = You know the square root of 16 =

= = = Look for the biggest squares that are factors: Write them as separate radicals = You know the square root of 9 =

If no square factors jump out at you, see if 4 goes into the number If no square factors jump out at you, see if 4 goes into the number. If not, try 9, then 25. = 27 has a square in it…..simplify it = Write them as separate radicals = You know the square roots of 4&9 = Multiply the 2 and 3 =

= Write them as separate radicals = You know the square root of 25 =

= 6 and 7 are factors – but they aren’t squares! This can’t be simplified

= = = = = 8 has a square in it…..simplify it Write them as separate radicals = You know the square roots of 9&4 = Multiply the 3 and 2 =
