3 = 0.4771, find the value of𝑙𝑜𝑔1081?30. If 𝑙𝑜𝑔10a) 0.7b) 0.9c) 1.1d) 1.3

Given that \(\log_{10} 3 = 0.4771\), we are tasked with finding the value of \(\log_{10} 81\).

First, recognize that 81 is a power of 3:
\[
81 = 3^4
\]

Using the logarithmic property \(\log_b(x^n) = n \log_b x\), we can write:
\[
\log_{10} 81 = \log_{10} (3^4) = 4 \log_{10} 3
\]

Substituting the given value of \(\log_{10} 3 = 0.4771\):
\[
\log_{10} 81 = 4 \times 0.4771 = 1.9084
\]

Now, comparing the calculated value to the options:
- (a) 0.7
- (b) 0.9
- (c) 1.1
- (d) 1.3

None of the provided answers match directly, but since \(1.9084\) rounds to approximately **1.9**, this suggests that the answer might have been truncated or rounded incorrectly.

Thus, **none of the given options seem to be correct** based on this calculation.
