When an index is applied to a fraction, we can apply the index to both the numerator & the denominator.
What pattern can you see? How can we complete the table? ÷ 2 ÷ 2 ÷ 2
What pattern can you see? How can we complete the table? ÷ 3 ÷ 3 ÷ 3
A negative indices means that instead of multiplying by the number many times, we divide by the number many times. A negative power is the reciprocal of the positive power.
A negative indices means that instead of multiplying by the number many times, we divide by the number many times.
How can we write this as a calculation? A negative indices will create the reciprocal , so a fraction will be ‘flipped’.

When an index is applied to a fraction, we can apply the index to both the numerator & the denominator.
To manipulate surds we can split them into factors and take the square root of each. If we have the square root of a fraction, we can apply the square root to the denominator & numerator.
How can we split this index into two operations? Negative: reciprocal Take the reciprocal Fraction: root
How can we split this index into two operations? Negative: reciprocal Take the reciprocal Fraction: cube root
How can we split this index into three operations? Negative: reciprocal Fraction: cube root Integer: square Take the reciprocal
