Mathematics 30-1 Quiz 4.2 - TS Value 8 PART A: MULTIPLE CHOICE/NUMERICAL RESPONSE This quiz includes multiple choice and numerical response questions. For multiple choice questions, select the best answer. For numerical response questions, enter the numerical values into the space provided. 1. Evaluate log: 2 - log: 1 + log: 16. A. B. A N w/usci/ w Hint: The expression contains logarithms with the same base. As such, the logarithms may be combined using logarithmic laws. 2. Express logaxvy, x > 0, y > 0 in terms of m and n, where logax = m and logy = n. A. mton B. -mn C. m+nz D. - ( m + n) Hint: Recall the radicand of a square root can be expressed as a power with an exponent of -. Expand the expression using logarithmic laws. 3. A correct expansion of the expression log. [ (a w/b ] is A. . 1 + logab - log.c' B. 4 + logab - logic C. 1+ 7 logab - log.c D. 4+ - logab - 3log.c Hint: Start by converting the radical to a power. Then, use the logarithmic laws to expand the expression
