Simplify the expression. write the answer using scientific notation. (2 × 10^13)^-2 a.-4×10^-26 b.0.25 ×10^-26 c.2.5×10^-27 d.2.5×10^-26

  C.  2.5×10^-27

Step-by-step explanation:

(2×10^-13)^-2 = 2^-2 × 10^(13×(-2)) = 1/4 × 10^-26

= 0.25 × 10^-26 = 2.5 × 10^-27

Your scientific or graphing calculator can compute and display this for you.

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
