Answer:
5 x^2 y^ (-3) z = ?
Step-by-step explanation:
We know the volume of a rectangular prism is given by
V = l*w*h
V = 2x^2 * y^-2 * ?
We are given the volume
V =10x^4 y^-5 z
Set the two equal
10x^4 y^-5 z = 2x^2 * y^-2 * ?
Divide each side by 2x^2 y^-2
10x^4 y^-5 z /2x^2 y^-2 = 2x^2 * y^-2 * ?/2x^2 * y^-2
10x^4 y^-5 z/ 2x^2 y^-2 = ?
Simplifying
10/2 * x^4/x^2 y^-5/ y^-2 z = ?
We know that a^b/ a^c = a^(b-c)
5 x^ (4-2) y^(-5 - -2) z = ?
5 x^2 y^ (-5 +2) z = ?
5 x^2 y^ (-3) z = ?
Answer:
28. 5x² × y^-3 × z
29. 2a⁵m⁵ × p^-2
Step-by-step explanation:
Volume = base area × height
1) 10x⁴z/y⁵ = 2x²/y² × height
Height = 10x⁴zy²/2x²y⁵
= 5x²z/y³
= 5x² × y^-3 × z
2. 14m⁸/a³p = 7p × 2m³/a⁸ × width
Width = 14m⁸a⁸/7a³p²m³
= 2a⁵m⁵/p²
= 2a⁵m⁵ × p^-2
