To evaluate the given expressions, we substitute the given values and perform the necessary calculations. (a) ln(a) = 0.693. (b) The expression is undefined. (c) ln(a¹b¹) = ln(6) = 1.792. (d) (ln(c)-²)(In(-12)) = 95.574.
Step-by-step explanation:
To evaluate the given expressions, we need to substitute the given values into the given equations and perform the necessary calculations.
(a) ln(a)
Substituting a = 2, we have ln(2) = 0.693 (approximately).
(b) ln(√6-³c²a-1)
Substituting a = 2, c = 5, we have ln(√6-³(5)²(2)-1)
= ln(√6-(375))
= ln(√(-369))
Since the argument inside the ln function is negative, the expression is undefined.
(c) ln(a¹b¹)
Substituting a = 2, ln(b) = 3, we have ln(2¹(3)¹)
= ln(2(3))
= ln(6)
Approximately, ln(6) = 1.792 (rounded).
(d) (ln(c)-²)(In(-12)
Substituting ln(c) = 5, we have (ln(5)-²)(In(-12))
= (5-²)(In(-12))
= (25-²)(In(-12))
= 23(4.158)
Approximately, 23(4.158) = 95.574 (rounded).
