DifficultyEasy -1.8 This is a straightforward recall question testing basic index laws with no problem-solving required. Part (i) applies the rule that any non-zero number to the power 0 equals 1, while part (ii) requires applying negative and fractional indices in a routine calculation (16^{-3/2} = 1/64). Both are standard textbook exercises requiring only direct application of memorized rules.

  1. Write down the value of \(\left( \frac { 1 } { 4 } \right) ^ { 0 }\).
  2. Find the value of \(16 ^ { - \frac { 3 } { 2 } }\).

3 (i) Write down the value of $\left( \frac { 1 } { 4 } \right) ^ { 0 }$.\\
(ii) Find the value of $16 ^ { - \frac { 3 } { 2 } }$.
