Step-by-step explanation:

26. 5*5*5*5=5^{4}

27. (-3)^{2}×(-5)^{2} =-3×-3×-5×-5

                           9×25=225

28.

.\frac{3*7^{2}*11^{8}  }{21*11^{3} } \\\frac{3*7^{2}*11^{8-3}  }{3*7} (\frac{x^{m} }{x^{n} } =x^{m-n} )(21=7*3)\\3^{1-1}*7^{2-1}*11^{5}\\3^{0} *7^{1} *11^{5}\\1*7*11*11*11*11*11\\1127357
