If loga x = s and loga y = t, then loga (xy)^2
If loga x = s and loga y = t, then loga (xy)2 = ?
- 2(s + t)
- s + t
- 4st
- 2st
- st
Answer
The correct answer is A.
By properties of logarithms,
loga (xy)2 = 2 loga (xy)
= 2(loga x + loga y)
= 2(s + t)
If loga x = s and loga y = t, then loga (xy)2 = ?
The correct answer is A.
By properties of logarithms,
loga (xy)2 = 2 loga (xy)
= 2(loga x + loga y)
= 2(s + t)
