(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}

=41×22×3×61=4^{-1}\times2^2\times3\times 6^{-1}

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

=12=\frac12
