Answer 2

Explicație pas cu pas:

b)

${3}^{20} \times {2}^{20} - {6}^{23} : {6}^{3} = {(3 \times 2)}^{20} - {6}^{23 - 3} = {6}^{20} - {6}^{20} = 0$

c)

${2}^{18} \times {12}^{18} : ( {6}^{16} \times {4}^{16} ) = {(2 \times 12)}^{18} : {(6 \times 4)}^{16} = {24}^{18} : {24}^{16} = {24}^{18 - 16} = {24}^{2} = 576$

d)

${75}^{38} : {25}^{38} - {( {3}^{19} )}^{2} = {(75:25)}^{38} - {3}^{19 \times 2} = {3}^{38} - {3}^{38} = 0$

e)

${26}^{27} : {13}^{27} : {2}^{ {5}^{2} } = {(26:13)}^{27} : {2}^{25} = {2}^{27} : {2}^{25} = {2}^{27 - 25} = {2}^{2} = 4$

f)

${10}^{64} : {2}^{64} - {5}^{ {4}^{3} } = {(10 : 2)}^{64} - {5}^{64} = {5}^{64} - {5}^{64} = 0$
