Answer:

2.5

Step-by-step explanation:

Since -5 is smaller than -2.5, the answer will be positive. To make life a little easier, you can simply just do 5 - 2.5 and get 2.5.

Hope this helped :)

What is the radical form of the expression?<br><br> (5x3y4)37<br> ↡
hram777 [196]

Option 4: \sqrt[7]{125x^9y^{12}} is the right answer

Step-by-step explanation:

Given expression is:

(\sqrt{5x^3y^4})^{\frac{3}{7}

In order to convert an exponent into radical form, the power should be in the form of 1/x where x is any number

so,

in case of 3/7, it will be broken down

(\sqrt{5x^3y^4})^{3*\frac{1}{7}}

The 1/7 will be converted into base of radical while 3 will be he exponent

\sqrt[7]{(5x^3y^4)^3}

Multiplying exponents

=\sqrt[7]{5^3x^{3*3}y^{4*3}}\\=\sqrt[7]{125x^9y^{12}}

Hence,

Option 4: \sqrt[7]{125x^9y^{12}} is the right answer

What is the simplified value of the exponential expression 27}?<br> оооо<br> 3<br> 9<br> 1/3<br> 1/9
iVinArrow [24]

<em>Note: Your exponential expression seems a little unclear. Because 27 is not an exponential expression.</em>

<em>But, I am assuming that your exponential expression is: </em>

  • \:27^{\frac{1}{3}}

<em>The reason is that my solution would still clear your concept about this topic, no matter what the question is. </em>

<em> </em>

Answer:

The simplified value of the exponential expression is:

27^{\frac{1}{3}}=3

Step-by-step explanation:

Assuming the exponential expression

\:27^{\frac{1}{3}}

\mathrm{Factor\:the\:number:\:}\:27=3^3

=\left(3^3\right)^{\frac{1}{3}}

\mathrm{Apply\:exponent\:rule}:\quad \left(a^b\right)^c=a^{bc},\:\quad \:a\ge 0

\left(3^3\right)^{\frac{1}{3}}=3^{3\cdot \frac{1}{3}}

=3^{3\cdot \frac{1}{3}}

=3^1

\mathrm{Apply\:exponent\:rule}:\quad \:a^1=a

=3

Therefore, the simplified value of the exponential expression is:

27^{\frac{1}{3}}=3

Help with this I don't know how to solve
Hunter-Best [27]

Answer:

86.53

Step-by-step explanation:

Area of Triangle Formula: A = 1/2bh

Pythagorean Theorem: a² + b² = c²

Step 1: Draw altitude and label numbers

If we draw a line down the middle, we can see that we get a perpendicular bisector and that we get 2 right triangles with a hypotenuse of 29 and a leg of 3. We need to find <em>h</em> using Pythagorean Theorem in order to use area formula:

3² + b² = 29²

b² = 29² - 3²

b = √832 = h

Step 2: Plug in known variables into area formula:

A = 1/2(√832)(6)

A = 3√832

A = 86.5332
