Write the expression 2ln3+ln8 as a single natural logarithm

What is the value of the expression below? (81^2)^1/8

Which equation represents a circle with a center at (–3, –5) and a radius of 6 units? (x – 3)2 + (y – 5)2 = 6 (x – 3)2 + (y – 5)2 = 36 (x + 3)2 + (y + 5)2 = 6 (x + 3)2 + (y + 5)2 = 36

Solve -2(4y + 6) = 52. 5 -5 8 -8 and !
