b.(-5)la puterea 41:[(-5) la puterea 22 *25 la puterea 30]
c.(-3 la puterea 3)la puterea 40:[(-3)la puterea 27 *27 la puterea 30]

Answer 1

[tex] ((-7)^{3})^{11} :[(-49) ^{8} *343^{5} ]= (-7)^{33} :[( -7^{2}) ^{8} * (7^{3})^{5} ]= 7^{33} : 7^{16+15} = 7^{33-31} = 7^{2} =49[/tex]

$(-5)^{41} :[(-5 )^{22} * (5^{2}) ^{30}]= (-5)^{41}: 5^{22-2*30} =- 5^{41-22+60} =- 5^{79}$

$( (-3)^{3} ) ^{40} :[(- 3)^{27} * (3^{3} )^{30} ]= -3^{120} : 3^{27-90} =- 3^{120-27+90} =-3 ^{183}$
