Given that the logarithm of a number is (bar{1}.8732), find, correct to 2 significant figures the square root of the number.

  • A.
    0.29
  • B.
    0.75
  • C.
    0.86
  • D.
    0.93
Correct Answer: Option C
Explanation

Let the number = d.

(log d = bar{1}.8732)

(log sqrt{d} = frac{bar{1}.8732}{2})

= (frac{bar{2} + 1.8732}{2})

= (bar{1}.9366)

(therefore sqrt{d} = Antilog (bar{1}.9366))

= 0.86
