Changes in water in the american southwest lake mead is an artificial lake formed by the hoover dam, covering parts of both arizona and nevada. it has a surface area of 640 km. the area has been experiencing a drought since 2000, and the water level has dropped 43 meters (140 feet). how many cubic kilometers (km) of water have disappeared during this drought? hint: recall that volume is equal to depth x length x width, and assume the area of the lake is the same at the surface as it is at 43 m depth.

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!

answer: b
