Evaluate `(563.4 xx root(3)(0.4773))/((6.15)^(3)).`

Answer» Let `x = (563.4 xx root(3)(0.4773))/((6.15)^(3)).` Then,
log x = log `563.4 + 1/3` log (0.4573) - 3 log (6.15)
`= 2.7508 + 1/3 (bar(1).6602) - 3 xx 0.7889`
`= 2.7508 + 1/3 (-3398) - 2.3667`
`= 2.7508 - 0.1133 - 2.3667`
= 0.2708
`rArr` x = antilog (0.2708) = 1.865.
Hence, the value of the given expression is 1.865.
