Differentiating with respect to time

Basic Power Rule:

f(x) = cxⁿ
f’(x) = c·nxⁿ⁻¹

Step-by-step explanation:

Step 1: Define

$l = 30 \ cm\\w = l\\\frac{dl}{dt} = 2 \ cm/h\\h = 20 \ cm\\\frac{dh}{dt} = 3 \ cm/h$

Step 2: Differentiate

Rewrite [VRP]: $V = l^2h$
Differentiate [Basic Power Rule]: $\frac{dV}{dt} = 2l\frac{dl}{dt} \frac{dh}{dt}$

Step 3: Solve for Rate

Substitute: $\frac{dV}{dt} = 2(30 \ cm)(2 \ cm/h)(3 \ cm/h)$
Multiply: $\frac{dV}{dt} = 360 \ cm^3/h$

Here this tells us that our volume is decreasing (ice melting) at a rate of 360 cm³ per hour.

Citrus2011 [14]

Answer:

$2^{3}$ ×5×3× $x^{2}$ × $y^{4}$

Step-by-step explanation:

$8xy^{4}$ = $2^{3}$ × $x$ × $y^{4}$

6 $x^{2} y$ = 2×3× $x^{2}$ × $y^{}$

10 $x^{2} y^{2}$ = 2×5× $x^{2}$ × $y^{2}$

$2^{3}$ ×5×3× $x^{2}$ × $y^{4}$
