If log x = \(\bar{2}.3675\) and log y = 0.9750, what is the value of x + y? Correct to three significant figures
- 1.18
- 1.31
- 9.03
- 9.44
-
9.46
The correct answer is: E
Explanation
log x = \(\bar{2}.3675\) ; log y = 0.9750
\(x = 10^{\bar{2}.3675} = 0.02331 \)
\(y = 10^{0.9750} = 9.441 \)
\(x + y = 9.4641 \approxeq 9.46\)
