Answer 1

Ответ:

2) (а⁶+b⁵) (a¹²-a⁶b⁵+b¹⁰)

4) (ab²c³+2) (a²b⁴c⁶-2ab²c³+4)

Answer 2

Ответ:

1)

${a}^{18} + {b}^{15}$

${a}^{18} = {( {a}^{3} )}^{6}$

${b}^{15} = {( {b}^{5}) }^{3}$

=>

${a}^{18} + {b}^{15} = {( {a}^{3} )}^{6} +{ ( {b}^{5} ) }^{3}$

2)

${a}^{3} {b}^{6} {c}^{9} + 8$

${a}^{3} = {(a)}^{3}$

${b}^{6} = {(b)}^{6}$

${c}^{9} = {( {c}^{3}) }^{3}$

=>

${a}^{3} {b}^{6} {c}^{9} + 8 = {(a)}^{3} {(b)}^{6} {( {c}^{3} )}^{3} + 8$
