A builder builds a brick wall that is 10m long and 1.5m high. The face of a brick is 20cm by 10cm. How many bricks will be needed to complete the wall?

10m×1.5m=15m squared total area of the wall

15×100=1500

1500÷200=7.5 bricks would be needed for that wall.

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!
