SL 1.7—Rational exponents and logarithm laws Topic Practice

How this is tested

• combine and rearrange log expressions, including quotient, power and change-of-base laws
• solve logarithmic equations by rewriting to a single log and checking the domain x>0 where required
• link exponential forms such as 1.105^t=e^(kt) to exact constants like k=ln(1.105)
