QUIZ 20 QUESTIONS hard Math 1 1 + 1 = 2 then a + a = 2aA^2A * a 2 1 + a = 1 + a then a + 3 = A + 33a4 3 1 + 1 + 1 = 3 then a + a + a = 3a3A^3 4 3 * 3 = 9 then a * a = 2aA^2A + 2 5 5/5 = 1 then a/a = A^201 6 25/5 = 5 then a^2/a = 12A 7 2a + a = 3a then 5a + 2a = 7a7A^7 8 2a * 3a = 6a^2 then 5a * 2a = 10a10a^27a 9 3a / 2a = 3/2 then 5a / 2a = 5aA/25/2 10 4a + 12a = 16a and a + 3 = a + 3 These terms are simplified. 4a + 12 = 16a164a + 12 11 A^2 * a^3 = a^5 reminder : "^" means "to the power of" then b^2 * b^3 = 5BB^5 12 A * a = a^2 then a * a * a = A3A^3 13 1/a * 1/a = 1/a^2 then 1/a * 1/a * 1/a = 1/a1/a^21/a^3 14 (a * a) / a = a then a^2 / a = 21/aA 15 A / (a * a) = 1/a then a / a^2 = A21/a 16 A * a * a * b * b / (a * b) = a^2 * b then a^3 * b ^2 / (a * b) = AbA^2 * b1/ab 17 2a + 3b + a + b = 3a + 4b then 5a + 4a + 2b + 6b = 175a + 6b9a + 8b 18 4a - 5a + b - 3b = -a - 2b then 5a - 4a - b + 3b = 3b3A + 2b 19 A^-1 = 1/a and a^-2 = 1/(a^2) also 1/(a^-1) = a so a^2 * a^-2 = 1 then (a^-1) / (a^-2) = A21/a 20 3(a + 1) = 3a + 3 distributive property 3a(3a + 5) = 9a^2 + 15 and negative -3a(2a + 4) = -6a^2 - 12a then 7b(2b + 4) = 4214b^2 + 28b-14b^2 - 28b A mistake in this Quiz ?
