Question

(1³+2³+3³) rays to the power -5/2

Answer 1

(1^3+2^3+3^3)^-5/2
= (1+8+27)^-5/2
= (36)-5/2
= (6^2)^-5/2
= 1/(6^2)^5/2
= 1/6^5
= 0.0001286008

Answer 2

Answer :

${(1 {}^{3} + {2}^{3} + {3}^{3}) }^{ \frac{ - 5}{2} } = {(1 + 8 + 27)}^{ \frac{ - 5}{2} }$

$= > {(36)}^{ \frac{ - 5}{2} } = \: { ({6}^{2}) }^{ \frac{ - 5}{2} }$

$= > {6}^{ \frac{ - 5}{2} \times 2 } = {6}^{ - 5} = { (\frac{1}{6}) }^{5}$

$= > { (\frac{1}{6}) }^{5} = 7776$

Hope this helps you mate☺☺
