a)(-4)⁷: (-4)⁵.(-4)=
b) √12.√3 =
c) (-5)⁷: (-5)⁵.(-5) =​

Answer 1

Respuesta:

a)(−4)5÷(−4)3=(−4)5−3=(−4)2=16

b) {( - 3)}^{3} \div {( - 3)}^{2} = {( - 3)}^{3 - 2} = {( - 3)}^{1} = - 3b)(−3)3÷(−3)2=(−3)3−2=(−3)1=−3

c) {( - 2)}^{4} \div ( - 2) = {( - 2)}^{4 - 1} = {( - 2)}^{3} = - 8c)(−2)4÷(−2)=(−2)4−1=(−2)3=−8

d) {( {8}^{6} )}^{2} \div {( {8}^{3} )}^{3} = {8}^{6 \times 2} \div {8}^{3 \times 3} = {8}^{12} \div {8}^{9} = {8}^{12 - 9} = {8}^{3} = 512d)(86)2÷(83)3=86×2÷83×3=812÷89=812−9=83=512
