Question

evaluate using log table (0.7634)^1/3/(272.3*15.2)^1/2​

Answer 1

[1/3log 0.7634 ] - [ 1/2 ( log 272.3 + log 15.2 ) ]

[ 1/3 × ( -1 + .8827) ] - [ 1/2 × ( 2.4351 + 1.1818) ]

[1/3× ( - 0.1173) ] - [ 1/2 × 3.6169]

(-0.0391) - 1.80845

= -1.84755

now we have to find antilog but the no. is in negative so we have to convert it into positive

-2+2-1.84755

= 0.15247

antilog of 0.15247 = 1420

we have to put decimal (n+1)

(-2+1) = -1

Antilog = 1.420 ans.
