Given that 3 = 0.4771 and 2 = 0.3010. We assume the logarithm is base 10. Problem (i): Calculate 0.72. Step 1: Express 0.72 as a fraction and then in terms of prime factors. 0.72 = (72)/(100) = (2^3 × 3^2)/(10^2) Step 2: Apply logarithm properties (a)/(b) = a - b and (xy) = x + y. 0.72 = ((2^3 × 3^2)/(10^2)) = (2^3 × 3^2) - (10^2) = (2^3) + (3^2) - (10^2) Step 3: Apply the logarithm property a^b = b a. = 3 2 + 2 3 - 2 10 Step 4: Substitute the given values and 10 = 1 (since we assume base 10). = 3(0.3010) + 2(0.4771) - 2(1) = 0.9030 + 0.9542 - 2 = 1.8572 - 2 = -0.1428 The value of 0.72 is -0.1428. --- Problem (ii): Calculate sqrt(56). Step 1: Rewrite the square root as an exponent
