The number in the monomial 125x¹⁸y³z²⁵ that needs to be changed to make the expression a perfect cube is 25
To determine the number to be changed in order to obtained a perfect cube, we shall determine the cube root of each entity. This is illustrated below
Cube root of 125
³√125 = 5
Cube root of x¹⁸
³√x¹⁸ = x⁶
Cube root of y³
³√y³ = y
Cube root ofz²⁵
³√z²⁵ = z^(25/3)
From the illustration above, we can see that 25 is not a perfect cube.
Thus, 25 needs to be changed in order for the expression 125x¹⁸y³z²⁵to be a perfect cube

Answer:
$130.68
Step-by-step explanation:
1 acre = 43,560 square feet
3/4 of 43560 = 32,670 (So that would be 76,230 sq ft in 1.75 acres because 43560 + 32670 = 76230)
We need to divide the total by 35 plots.
76230 / 35 = 2178, using long division.
2,178 square feet is just one plot of 35. We need to multiply 2178 by 0.06.
