3 1 1 Evaluate: 6 19 502 3. Compute 10P6 and 10C6. 4. Write as a single logarithm: 2 log (x2 - 1) - 2 log y - 3 log (x + 1) + log (y + xy') [2x - 4y + z = 2 5. Use Cramer's rule to solve for x: 2y3z = -10 (-3x + 2y = -1 6. Use a calculator to aid in finding: (a) log6 15 (b) log15 6 7. Find the exact value of sin 345 by using the identity for sin (A + B) and the fact that 345 = 120 + 225. 8. Solve forx: log4 x = log4 x 9. Write the three cube roots of -27 in rectangular coordinates. Give exact answers. 3 1 1 Evaluate: 6 19 502 3. Compute 10P6 and 10C6. 4.
