Answer 2

To simplify the expression:

log(218) + log(225/9) + log(21/25)

You can use the properties of logarithms to combine these terms. Specifically, you can use the product rule and the quotient rule for logarithms:

1. Product Rule: log(a) + log(b) = log(a * b)
2. Quotient Rule: log(a) - log(b) = log(a / b)

So, applying these rules to your expression:

log(218) + log(225/9) + log(21/25) = log(218 * (225/9) * (21/25))

Now, you can simplify the inside of the logarithm:

218 * (225/9) * (21/25) = 218 * 25 * 21 / (9 * 25) = (218 * 21) / 9

Now, the expression inside the logarithm becomes:

log((218 * 21) / 9)

You can further simplify this expression:

(218 * 21) / 9 = 4578 / 9 = 509.33 (approximately)

So, the simplified expression is:

log(509.33)

You can compute the value of this logarithm using a calculator:

log(509.33) ≈ 2.7071

So, log(218) + log(225/9) + log(21/25) ≈ 2.7071
