\sqrt[n]{a^m}=\a^\frac{m}{n}


\sqrt[4]{x^{10}}=x^\frac{10}{4}=x^{2\frac{2}{4}}=x^2\cdot x^\frac{2}{4}=x^2\sqrt[4]{x^2}


Used:\\\\a^n\cdot a^m=a^{n+m}

Try to solve for x, i cant figure it out
snow_lady [41]

Answer:

Step-by-step explanation:

From the upper isosceles triangle,

The answer is: x=±√5y [Note: If and only if at the lower triangle is NOT isosceles]

Exterior angle to the isosceles triangle = 2(2x^2 – 2x) [because the exterior angle of a triangle is equal to               the sum of two opposite interior angles]

Therefore, the exterior angle = 4x^2 – 4x

Also,

The exterior angle is equal to the sum of the two interior base angles of the lower triangle

Thus, 4x^2 – 4x=(3x^2+4x) + (5y – 8x)

By collecting like terms,

4x^2 – 3x^2 – 4x – 4x + 8x – 5y = 0

x^2 – 5y = 0

x^2 = 5y

By taking the square root of both sides

x=±√5y

The following chart shows a store’s coat sales for two years.
STALIN [3.7K]

Answer:

Sales of trench coats increased 8.3 percentage points faster than total coat sales.

Step-by-step explanation:

<u>2006:</u>

top coats is 297,

parkas is 210,

jackets is 213,

raincoats is 137,

trench coats is 103

Total: 297+210+213+137+103=960

<u>2007:</u>

topcoats is 223,

parkas is 210,

jackets is 285,

raincoats is 259,

trench coats is 127

Total: 223+210+285+259+127=1,104

<u>Percent increase in total sales:</u>

\dfrac{1,104-960}{960}\cdot 100\%=15\%

<u>Percent increase in sales of trench coats:</u>

\dfrac{127-103}{103}\cdot 100\%\approx 23.3\%

Since 23.3\%-15\%=8.3\%, sales of trench coats increased 8.3 percentage points faster than total coat sales.
