Squaring & Square Roots

Square 2 2 = 2 x 2 = = 4 x 4 = = 1.75 x 1.75 = = 0.12 x 0.12 = Any Number 2 = Any Number x Any Number

Square Root 4 1/2 = 4 = 2 4 1/2 = 2 x 2 = /2 = ? X ? = ? 1.1 x 1.1 = x 1.4 = x 1.3 = 1.69

Square Root /2 = ? X ? = ? ……. 1.3 x 1.3 = x 1.33 = x = x = x =

Square Root /2 = ? X ? = ? ……. 1.3 x 1.3 = x = 1.75

Cubing & Cube Roots

Cubed 2 3 = 2 x 2 x 2 = = 4 x 4 x 4 = = 1.75 x 1.75 x 1.75 = = 0.12 x 0.12 x 0.12 =

Cubed 2 3 = 2 x 2 x 2 = = 4 x 4 x 4 = = 1.75 x 1.75 x 1.75 = = 0.12 x 0.12 x 0.12 =

Cubed Any Number 3 = Any Number x Any Number x Any Number

Checking Cubes = 0.12 x 0.12 x 0.12 = ÷ 0.12 = ÷ 0.12 = 0.12

Cube Root 8 1/3 = 8 = /3 = 2 x 2 x 2 = /3 = ? X ? = ? 1.1 x 1.1 x 1.1 = x 1.2 x 1.2 = OR 1.21 x 1.21 x 1.21 =
