The #’s 1, 4, 9, 16, 25 .…are called The #’s 1, 4, 9, 16, 25 .…are called perfect squares / square numbers The #’s 1, 4, 9, 16, 25 .…are called perfect squares / square numbers because they have whole # square roots or because squares with those areas would have sides that are whole #’s The #’s 1, 4, 9, 16, 25 .…are called perfect squares / square numbers because they have whole # square roots or because squares with those areas would have sides that are whole #’s The #’s 1, 8, 27, 64, 125 .…are called The #’s 1, 4, 9, 16, 25 .…are called perfect squares / square numbers because they have whole # square roots or because squares with those areas would have sides that are whole #’s The #’s 1, 8, 27, 64, 125 .…are called perfect cubes Cube Roots The #’s 1, 4, 9, 16, 25 .…are called perfect squares / square numbers because they have whole # square roots or because squares with those areas would have sides that are whole #’s The #’s 1, 8, 27, 64, 125 .…are called perfect cubes because they have cube roots that are whole numbers or because cubes with those volumes would have sides that are whole numbers Cube Roots The #’s 1, 4, 9, 16, 25 .…are called perfect squares / square numbers because they have whole # square roots or because squares with those areas would have sides that are whole #’s The #’s 1, 8, 27, 64, 125 .…are called perfect cubes because they have cube roots that are whole numbers or because cubes with those volumes would have sides that are whole numbers Cube root – the cube root of a #/term is a #/term that multiplies by itself 3 times to equal the original #/term Ex. The cube root of 8 = 2 since 2x2x2 = 8 Cube Roots Determine the sides of the following cubes a) b) V = 64 c) V = 1728 V = 1000 Cube Roots Determine the sides of the following cubes a) b) 4 V = 64 c) 12 V = 1728 10 V = 1000 Cube Roots Determine the cube roots of the following a) b) c) d) e) f) 27000 1331 343 15.625 10 512x3 Cube Roots Determine the cube roots of the following a) b) c) d) e) f) 27000 1331 343 15.625 10 512x3 30 11 7 2.5 2.15 8x
