Correct answer is E
log x = ˉ2.3675 ; log y = 0.9750
x=10ˉ2.3675=0.02331
y=100.9750=9.441
x+y=9.4641≊
Evaluate using the logarithm table, log(0.65)2
1.6258
0.6272
0.6258
3.6258
1.6272
Correct answer is D
log(0.65)2 = 2log(0.65) but log0.65 = 1.8129
∴2 x 1.8129 = 3.6258
Simplify \frac{\log \sqrt{8}}{\log 8}
1/3
1/2
1/3log√2
1/3log√8
1/2log√2
Correct answer is B
\frac{\log \sqrt{8}}{\log 8}
= \frac{\log 8^{\frac{1}{2}}}{log 8}
= \frac{\frac{1}{2} \log 8}{\log 8}
= \frac{1}{2}
Given that 1/3log10 P = 1, find the value of P
1/10
3
10
100
1000
Correct answer is E
1/3log10P = 1
log10P1/3 = log1010
P1/3 = 10 P = 1000
