Expression: 3⁴ . 2³
= 3 * 3 * 3 * 3 * 2 * 2 * 2
= 81 * 8
= 648
In short, Your Answer would be: 648
Hope this helps!
The expression is:

Why?
From the statement we know that the spaceship travels 3 times faster each minute that it traveled during the minute before, it can be expressed using an exponential function, its base will be the starting speed (during the first minute).
The expression will be:

Have a nice day!
Answer:
The GCF for the variable part is
k
Step-by-step explanation:
Since
18
k
,
15
k
3
contain both numbers and variables, there are two steps to find the GCF (HCF). Find GCF for the numeric part then find GCF for the variable part.

Using the universal measurement
Kilo, hecto, deca, unit, deci, centi, milli
Kilometer, hectometer, decameter, meter, decimeter, centimeter, millimeter
From unit you would move three time to the left from your decimal point on your starting number 250. You would move it three times to the left because meter to kilometer is three decimals to the left
A way I remember my universal measurements is king (k-kilo), Henry (h-hecto), died (d-deca), unexpectedly (u-unit as in liters, meters, grams) drinking (d-deci), chocolate (c-centi) milk (m-milli)
