A and b are positive integers and a–b = 3. Evaluate the following: 27^ (1/3 b)/9^ (1/2 a)
maxonik [38]

Answer:

1/27

Step-by-step explanation:

27^(b/3)/9^(a/2) = (27^(1/3))^b/(9^(1/2))^a = (3^b)/(3^a) = 3^(b-a)

= 3^(-(a-b)) = 3^-3 = 1/3^3 = 1/27

Solve open parentheses square root of 7 close parentheses to the 6 x power = 49x−6.
LUCKY_DIMON [66]
(sqrt7)^6x = 49x - 6

There is no easy way to solve this . Drawing a graph will give a good approximation.

Draw  y = (sqrt7)66x

and y = 49x - 6     and see where they intersect

Ill draw it on desmos graphing tool and give you the link.
