Please help me Algebra 1

Oduvanchick [21]

Answer:

a. $\sqrt{x^n}$ = $x^\frac{n}{2}$

b. $\sqrt{x^n} = x^\frac{(n-1)}{2}\sqrt{x}$

Step-by-step explanation:

a) When n is even, then it is divisible by 2. Because of this, you can write:

$\sqrt{x^n} = (x^n)^\frac{1}{2}$

$\sqrt{x^n} = x^\frac{n}{2}$

b) When n is odd, then n - 1 is even. This would make it divisible by 2, and there would be a remainder of 1, so we can write:

$\sqrt{x^n} = (x^n^-^1^+^1) ^\frac{1}{2}$

$\sqrt{x^n} = (x^n^-^1$ × $x)^\frac{1}{2}$

$\sqrt{x^n} = x^\frac{(n-1)}{2}$ × $x^\frac{1}{2}$

$\sqrt{x^n} = x^\frac{(n-1)}{2}\sqrt{x}$

Two trapezoids have areas 54 cm2 and 24 cm2. Find their ratio of similarity.

malfutka [58]

$\bigg( \dfrac{Length_1}{Length_2} \bigg)^ 2 = \dfrac{Area_1}{Area_2}$

$\bigg( \dfrac{Length_1}{Length_2 }\bigg )^ 2 = \dfrac{54}{24}$

$\dfrac{Length_1}{Length_2} = \sqrt{\dfrac{54}{24} }$

$\dfrac{Length_1}{Length_2} = \sqrt{\dfrac{9}{4} }$

$\dfrac{Length_1}{Length_2} = \dfrac{3}{2}$

$\text {Ratio of similarity of the two trapeziums =} 3 : 2$
