What is log x + log y - 2 log z written as a single logarithm? log2xyz log xz^2/y log 2z/xy log xy/z^2

D) log (xy/z^2)

Step-by-step explanation:

The given expression is log x + log y - 2 log z

Here we use log rules to simplify this.

Product rule: log x + log y = log (xy)

Quotient rule : log x - log y = log(x/y)

Power rule: log(x^y) = y.log(x)

Using the product rule

log x + log y - 2 log z

= log(xy) - 2 log z

Use the power rule now.

= log(xy) - log z^2

Now we have to use the Quotient rule and simplify.

= log

D) log (xy/z^2)

Thank you.

constant acceleration- a

constant velocity- c

no velocity or acceleration- b

explanation:

for body moving with a constant acceleration, the rate of change of displacement changes over time. this is proven by the increasing gradient of the curve (a) against time.

a body that is moving at constant velocity covers equal distances over equal periods of time, thus the straight line with a constant gradient c.

a stationary body   covers no displacement as time elapses. thus the flat line with   zero gradient.

at least two
