Pablo simplified the expression (2 Superscript negative 4 Baseline) Superscript negative 2 as shown.
(2 Superscript negative 4 Baseline) Superscript negative 2 = 2 Superscript negative 4 times 2 Baseline = 2 Superscript negative 8
Which statement explains Pablo’s error?
He should have added the exponents instead of multiplying them.
He should have divided the exponents instead of multiplying them.
He should have found 8 as the exponent, not –8.
He should have written 2 Superscript negative 8 as StartFraction 1 Over 2 Superscript 8 Baseline EndFraction.

Step-by-step explanation:
Given the expression simplified by Pablo as![(2^{-4})^{-2}](/tpl/images/0687/6362/07cba.png)
On simplification we have;
According to one of the law of indices![(a^{m})^{n} = a^{mn}](/tpl/images/0687/6362/db5d4.png)
Applying this law to the question will give;
Based on the calculation above, the exponent of 2 is 8 which means that Pablo should have found 8 as the exponent, not –8.
