Which equation justifies why nine to the one third power equals the cube root of nine?
AVprozaik [17]

Answer:

nine to the one third power all raised to the third power equals nine raised to the one third times three power equals nine

Step-by-step explanation:

we know that

The <u><em>Power of a Power Property</em></u> , states that :To find a power of a power, multiply the exponents

so

(a^{b})^{c}=a^{b*c}

In this problem we have

9^{\frac{1}{3}} =\sqrt[3]{9}

Remember that

\sqrt[3]{9}=9^{\frac{1}{3}}

Raise to the third power

[9^{\frac{1}{3}}]^3

Applying the power of power property

9^{\frac{3}{3}}

9^{1}

9

therefore

nine to the one third power all raised to the third power equals nine raised to the one third times three power equals nine

PLEASE HELP !!!!!!!!!!!!!!!!!!!!!!!<br><br>QUESTION ATTACHED
DIA [1.3K]

Angle-5 and angle-7 are 'vertical angles', so they're equal,
and we can write ...
                                           <u>10x- 9  =  9x</u>

Subtract  9x  from each side:  x - 9 = 0

Add  9  to each side:              <u> x     =  9</u>

Now that we know what 'x' is, we can find the size of Angles-5  and -7 .

Angle-7  =  9x  = 81° .

Now look at Angle-6 ... the one that's the answer to the problem.

Angle-6  and -7 together make a straight line, so they must
add up to 180°.

                                     <u>Angle-6  +  81°  =  180°</u>

Subtract 81° from each side:    Angle-6  =  <em>99° .</em>
