1.Condense the expressions to the logarithm of a single quantity: a) b) 2. Simplfy the expression by removing the common factor with the smaller exponent: 3. Perform the operations and simplify: (or you might consider a slightly different form is "simplest") 4. Use the vertex formula to determine the vertex of the graph of the function and write the function in standard form: 5. Solve the equation: Cube, then factorize as (8x + 1)(2x  4). Hence x = 1/8 or 2. 6. Since the exponent is zero, the value of the expression is 1.

1. Solve each radical in simplest form: a) b) 2. Simplify by rationalizing the denominator: 3. Solve: x = (1/2  1/2)/(3/2  2/7) = 14/17 4. Write in standard form: Which three of these four did you need help on?
