(64)−13(8)23(27)13(36)−12=?(64)^{-\frac13}(8)^{\frac23}(27)^{\frac13}(36)^{-\frac{1}{2}}=?

A1/4

B1/2

C1/8

D1/12

Answer:

B. 1/2

Read Explanation:

64(−13)×8(23)×27(13)×36(−12)64^{(\frac{-1}{3})}\times 8^{(\frac23)}\times27^{(\frac13)}\times36^{(\frac{-1}{2})}

=(43)−1/3×(23)2/3×(33)1/3×(62)−1/2=(4^3)^{-1/3}\times(2^3)^{2/3}\times(3^3)^{1/3}\times(6^2)^{-1/2}

=43×−1/3×23×2/3×33×1/3×62×−1/2=4^{3\times{-1/3}}\times2^{3\times{2/3}}\times3^{3\times{1/3}}\times6^{2\times{-1/2}}

=4−1×22×3×6−1=4^{-1}\times2^2\times3\times 6^{-1}

=14×4×3×16=\frac14\times4\times3\times\frac16

=12=\frac12
