Answer:

$\displaystyle 2^{\frac{6}{5}}=2\sqrt[5]{2}$

Step-by-step explanation:

<u>Fractional Exponents</u>

An expression like

$\displaystyle a^{\frac{n}{m}}$

can be expressed as a radical of the form:

$\sqrt[m]{a^n}$

We have the expression:

$\displaystyle 2^{\frac{6}{5}}$

Its equivalent radical form is:

$\displaystyle 2^{\frac{6}{5}}=\sqrt[5]{2^6}$

Since the exponent is greater than the index of the radical, we can take 2 out of it by following the procedure:

$\sqrt[5]{2^6}=\sqrt[5]{2^5\cdot 2}$

Taking out $2^5$ from the radical:

$\sqrt[5]{2^6}=2\sqrt[5]{2}$

Thus:

$\displaystyle 2^{\frac{6}{5}}=2\sqrt[5]{2}$

Jenna and Heidi together have $60. Jenna has $9 more than twice Heidi’s amount. How much money does each have?

Marina86 [1]

Jenna has $43 and Heidi has $17.

Step-by-step explanation:

Total amount = $60

Let,

Amount of Jenna = x

Amount of Heidi = y

According to given statement;

x+y=60 Eqn 1

x=2y+9 Eqn 2

Putting value of Eqn 2 in Eqn 1;

$(2y+9)+y=60\\2y+9+y=60\\3y=60-9\\3y=51$

Dividing both sides by 3,

$\frac{3y}{3}=\frac{51}{3}\\y=17\\$

Putting y=17 in Eqn 2

$x=2(17)+9\\x=34+9\\x=43$

Jenna has $43 and Heidi has $17.
