### 8x to the second power times 3x to the second power?

8x to the second power times 3x to the second power
(8x)2 + (3x)2 = 64x2 + 9x2 = 73x2
is one possibility, except the problem called for multiplication
which would make the answer 64x squared times 9x squared = 576x to
the fourth power
It could also be read this way: 8x squared times 3x squared
equals 24x to the fourth power. I wish my computer would do those
cool little twos.

### A signal travels through a transmission medium and its power is reduces to one fourth find attenuation?

We have to read the question carefully to be sure of the final
power
after it's reduced.
If the question had said "reduces one fourth" or "reduces
by one fourth",
then the final power would have been 3/4 of the initial
power.
But the question says "reduces to one fourth",
which says that the
final power is 1/4 of the initial power.
Attenuation = 10 log [ (final power)/(initial power)] = 10 log (
1/4 ) = -6.02 dB
