Answer:
Explanation:
(a) To work out the value of 64 - 1/2, we first need to understand that -1/2 is the same as raising the number to the power of -1/2. So, 64 -1/2 can be written as 64^(-1/2)
The value of 64^(-1/2) is equal to 1/√(64) = 1/8
(b) To work out the value of 81 - 1/2, we can write it as 81^(-1/2)
The value of 81^(-1/2) is equal to 1/√(81) = 1/9
(c) To work out the value of 64 - 1/3, we can write it as 64^(-1/3)
The value of 64^(-1/3) is equal to 1/∛(64) = 1/4
(d) To work out the value of 125 - 1/3, we can write it as 125^(-1/3)
The value of 125^(-1/3) is equal to 1/∛(125) = 1/5
Note: √ represents square root and ∛ represents cube root
