Which expression is the simplest form of...
Lemur [1.5K]

Answer:

The answer is option A

Step-by-step explanation:

<h3>( {x}^{ -  \frac{4}{7} } )^{7}</h3>

Using the rules of indices

That's

<h3>( { {a}^{x} })^{y}  =  {a}^{x \times y}</h3>

Simplify the expression

We have

<h3>( { {x}^{ -  \frac{4}{7} } })^{7}  =  {x}^{ -  \frac{4}{7} \times 7 }   \\  =  {x}^{ - 4}</h3>

Again using the rules of indices

That's

<h3>{x}^{ - y}  =  \frac{1}{ {x}^{y} }</h3>

The final answer is

<h3>\frac{1}{ {x}^{4} }</h3>

Hope this helps you

Ricardo spends 2 2/3 hours practicing soccer on
ladessa [460]

Answer:

10 7/12 hours

Step-by-step explanation:

so we have to multiply 2 2/3 twice since he does that many hours for 2 days. We then have to multiply 1 3/4 three times since he does that many hours for 3 days. Lets first convert 2 2/3 into a mixed fraction. 2 2/3 = 3 times 2 =6 +2=8 over 3. 1 3/4=4 times 1=4+3=7 over 4. 8/3 times 2 equals 16/3 which eqials

5 1/3 hours. 7/4 times 3 equals to 21/4 which equals to 5 1/4. Lets now add

5 1/3 and 5 1/4. 5+5=10 but the fractions are not the same. Therefore, we need to make it to a common denominator. 4 times 3 equals to 12 so 4/12 plus 3/12 equals 7/12. Final answer equals to 10 7/12.
