Penjelasan dengan langkah-langkah:

A :

${5}^{ - 1} + {10}^{ - 2} \ \ = frac{1}{5} + frac{1}{ {10}^{2} } \ \ = frac{1}{5} + frac{1}{100} \ \ = frac{20 + 1}{100} \ \ = frac{21}{100} \ \ hasil = frac{21}{100}$

B :

${( {10.000}^{ frac{3}{4} } )}^{ frac{1}{3} } \ \ = {( { {10}^{4} )}^{ frac{3}{4} } )}^{ frac{1}{3} } \ \ = {10}^{4 times frac{3}{4} times frac{1}{3} } \ \ = {10}^{1} \ \ = 10$
