Hoover dam, in the united states, is 233 meters high. ertan dam, in china, is 240 meters high. write and evaluate a numerical expression to find the difference between the heights of the two dams.

Numerical expression for the difference in their heights

The difference in their heights= 7 meters

Step-by-step explanation:

Given: The height of the Hoover Dam, in the United States = 233 meters

The height of Ertan Dam, in China = 240 meters

let h be the difference in their heights

The difference between the heights of the two dams is given by the numerical expression

Therefore, the difference the heights of the two dams is 7 meters.

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!
