I need help. I will give 100pts. Reese simplified this expression. What error did he make?

(10m^(3)n^(5))/(5mn^(2))=(10(mn)^(8 ))/(5(mn)^(2))=2(mn)^(6)

He did not make an error because 2(mn)6 is correct.

He did not divide by 5mn2.

He used a law of exponents on factors with different bases.

He should have divided the exponents for a final answer of 2(mn)4.

5 * (2m + n)

Step-by-step explanation:

10m2 - 5mn - 5n2

answer: was that a question or answer?

step-by-step explanation:

answer: the answer is (b) amie should have multiplied

step-by-step explanation: given a sphere and a cylinder with same radius and height.

let, 'r' be the radius of the cylinder and sphere and 'h' be the height of the cylinder. according to the question,

r = h.

now, the volume of the sphere will be

and the volume of the cylinder will be

therefore, we have

thus, ammie should have multiplied the volume of the sphere
