Final answer:
The solutions to the equation a^2 = 64/225 are a = 8/15 and a = -8/15, corresponding to options (a) and (b). These solutions are found by taking the square root of both sides of the equation.
Step-by-step explanation:
To find the solution(s) to the equation a^2 = 64/225, we need to take the square root of both sides of the equation. Doing this yields two solutions because the square root of a number can be both positive and negative. Therefore, the solutions are a = √(64/225) and a = -√(64/225).
The square root of 64 is 8, and the square root of 225 is 15, so the solutions simplify to:
These correspond to options (a) and (b) respectively, so the correct answers are:
a. a = 8/15
b. a = -8/15
