Answer 1

${5}^{54} = {5}^{27 \times 2} = {( {5}^{27} )}^{2} = > p.p$

${17}^{26} = {17}^{13 \times 2} = { ({17}^{13}) }^{2} = > p.p$

${7}^{58} = {7}^{29 \times 2} = {( {7}^{29}) }^{2} = > p.p$

${25}^{31} = {( {5}^{2} )}^{31} = { ({5}^{31} )}^{2} = > p.p$

${4}^{53} = {( {2}^{2} )}^{53} = { ({2}^{53} )}^{2} = > p.p$

${13}^{34} = {13}^{17 \times 2} = { ({13}^{17}) }^{2} = > p.p$

${9}^{29} = {( {3}^{2}) }^{29} = { ({3}^{29}) }^{2} = > p.p$

${49}^{27} = {( {7}^{2}) }^{27} = {( {7}^{27}) }^{2} = > p.p$
