Answer : The correct option is, x^{\frac{2}{3}}

Step-by-step explanation :

The given expression is :

(x^{\frac{4}{3}}\times x^{\frac{2}{3}})^{\frac{1}{3}}

First we have to solve the term present in the bracket.

Identity used : x^a\times x^b=x^{(a+b)}

\Rightarrow (x^{(\frac{4}{3}+\frac{2}{3})})^{\frac{1}{3}}

By the adding the powers of 'x', we get:

\Rightarrow (x^{\frac{6}{3}})^{\frac{1}{3}}

\Rightarrow (x^{2})^{\frac{1}{3}}

Now we have to use identity (x^{a})^b=x^{ab}, we get :

\Rightarrow (x)^{(2\times \frac{1}{3})}

\Rightarrow (x)^{\frac{2}{3}}

Therefore, the correct option is, x^{\frac{2}{3}}

An item is regularly priced at 85$. It is on sale for 80% off the regular price. How much is discounted from the regular price?
laila [671]

$68 is discounted from the regular price.

To find this, you first divide 80% by 100 to get 0.8 (the decimal form of the percentage). Then, simply multiply 0.8 by 85 (or vise verse) to get $68. Since the question is asking for how much is discounted from the regular price, the final answer would be $68.

I hope this helps!

A factory packed 9600kg of flour in to small bags and large bags. Each small bag contained 3kg of flour and each large bag conta
yawa3891 [41]

Answer:

696 large bags of flour were packed.

Step-by-step explanation:

Let large bags of flour be 'y'

Let small bags of flour be 'x'. That is x=2040 (according to the question)

(3 \times x) + (5 \times y) = 9600

(3 \times 2040) + ( 5 \times y) = 9600

(6120) + (5 \times x) = 9600

(5 \times x) = 9600 - 6120

(5 \times x) = 3480

x = 3480  \div 5

x = 696
