Using laws of exponents, what are three equivalent forms of the expression 5^-2 (i’ve already got 1/5^2 and 0.04)

expression #3 is not equivalent. the others are.

a² + b²= c²

24² + 7² = c²

c= 25

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
