There is a large number of cubes in a bag. Jason wants to work out an estimate for the number of cubes in the bag.
He takes at random 10 cubes from the bag.
He puts a mark on each cube and then puts each cube back in the bag.
Jason shakes the bag and then takes at random 20 of the cubes.
There is a mark on 3 of the cubes.
Work out an estimate for the total number of cubes in the bag

step-by-step explanation:

the answer is:

the answer is:

to solve the problem, we need to remember the quotient of power property, it's defined by the following relation:

if we have a quotienf of powers that have the same base, we need to keep the same base and subtract the exponent of the denominator power to the exponent of the numerator power.

so, we are given the expression:

then, calculating we have:

hence, the answer is:

have a nice day!
