Write 230,000,000,000 in scientific notation. Evaluate: 30 - 12÷3×2 = Evaluate: |4 - 8(3 - 12)| - |5 - 11| = Evaluate: -18 + 4(6 ÷ 2)2 Evaluate: 11 + sqrt(-4 + 6×4÷3) Simplify: 12x3 - 3(2x3 + 4x -1) - 5x + 7 Simplify: (x4 / x3)3 Simplify: (3x2y-2)3 / (9xy3)3 Simplify: (2x-3y4)3(x3 + y)0 / (4xy-2)3 Write as a mathematical inequality:"9 is less than the product of M and N". Find the slope of the line perpendicular to the line y = (1/3)x - 7
