Given that a = log 7 and b = \(\log\) 2, express log 35 in terms of a and b.
a + b + 1
ab - 1
a - b + 1
b - a + 1
Explicaţie
\(\frac{\log 7 \times \log 10}{\log 2}\)
log 7 x log 10 \(\div\) log 2
a + 1 - b
a - b + 1
\(\frac{\log 7 \times \log 10}{\log 2}\)
log 7 x log 10 \(\div\) log 2
a + 1 - b
a - b + 1
