Describe the error sadie made, and explain how to find the correct answer.

The answer to your question is below

Step-by-step explanation:

Sadie should have left inside the root an exponent lower than the root and the power of "a" is higher than "2", the root is squared.

Right solution

54 = 3² 6

a⁷ = a⁶ a

b³ = b² b

                 =

                =

               =

the terms of a geometric sequence can be found by beginning with the first term and multiplying by the common ratio repeatedly. a recursive formula for a geometric sequence with common ratio r is given by an=ran−1 a n = r a n − 1 for n≥2 n ≥ 2 .
