Answer:
I) 4*4*4= 4³
4*4= 4²
ii) 4 to the power of -1 ( It is a law, that in negative exponents it will be done in reciprocal and solved by applying exponents , here it is 1¹/4¹ which is = 1/4)
4 to the power of -3
iii) 9 to the power of -1
9 to the power of-2

Please refer to my attachments for solutions.
Step-by-step explanation:
When doing questions of this nature, unfortunately you have to use the trial-and-error approach, starting with the attempt of rewriting any pairs of numbers in terms of exponents with the smallest positive integer base 2. If not possible, increase the base and try it again until you succeed. Note that mastering laws of exponents will make this task significantly easier (even the question is telling you to use laws of exponents to solve them).
Hope it helps :)
