Brady can draw 2 rectangular boxes, both the same size and shape, break the top one up into 4 parts and color in 3 of the 4 boxes, this represents the fraction 3/4. Break the second box up into 8 parts and color in 7 of them. You will see that 7/8 is more than 3/4.

Which expression is equivalent to ^3√216x^27? 6x3 6x9 72x3 72x9
hichkok12 [17]
To solve this problem you must apply the proccedure shown below:

 \sqrt[3]{6^3 x^{27} }
 3. You have that 6^3 and the exponent 27&#10; are divisible by index 3&#10;. Therefore, you have:
 \sqrt[3]{216 x^{27} } =6 x^{9}
 Therefore, as you can see,
 the answer is the option, which is: 6 x^{9} &#10;
