Question 996322: I have a question about the logarithmic equations. I'll use log[a, b] where a is the base of the logarithm.
Is
log[sqrt3,(1-x)^2] - log[sqrt3, (3-x)] < 2
equal to
2 * log[sqrt3, (1-x)] - log [sqrt3, (3-x)]<2
If they're not equal, why aren't they? Isn't the logarithm property of exponent is log(1-x)^2 = 2 * log(1-x)?

Question 996427: Write an inequality and solve
CATEGORY WIND SPEED
1 74-95 mi/hr
2 96-110 mi/hr
3 111-130 mi/hr
4 131-155 mi/hr
5 156+ mi/hr
QUESTION:
The Saffir-Simpson Hurricane Scale rates a storm intensity by its sustained wind speed. By the time a hurricane reached the coast its sustained winds had decreased by 25 mi/hr, so it was down graded to a category 3 hurricane. Determine the possible sustained wind speeds of the hurricane at its peak.
