In a mathematics workshop, the instructor demonstrated the simplification of complex mixed numbers using step-by-step breakdowns.
 
Following the lesson, the students were tasked with solving a challenging expression to test their proficiency with fractions.
 
Answer the following:
 
(i) \(7^{12} \times 7^{10}\) \(=\) ii
 
(ii) \(\frac{7^{12}}{7^{10}}\) \(=\) ii
 
(iii) \((7^{12})^{10}\) \(=\) ii
 
(iv) \(7^{0}\) \(=\)
