Cassandra argues that (6 2/3)6 can be simplified to 6(6 2/3), but Rafael argues that the exponent 6 2/3 should be replaced with another number. Enter the number that the exponent 6 2/3 should be replaced with.

Assuming you mean (6^2/3)^6, the exponent 6 2/3 in the simplification should be replaced with 4

Step-by-step explanation:

Apply the power rule and multiply exponents.

6 ^2 /3  * 6

Cancel the common factor of  3

6 ^2 *2

Multiply  2  by  2 .

6 ^4

the answer is: the length is 5/6 yards.

step-by-step explanation:

rick has $1400 and sally has $1500

step-by-step explanation:

to find amount of money rick has after 10 years :

principal = $1000 , time = 10 years , rate = 4% annually

to find amount of money sally has after 10 years :

her friend gives to pay her $50 per year, therefore money she has after 10 years = 50 × 10 = $500

also, sally gets $1000 after 10 years,

therefore, total amount of money sally has after 10 years = 500 + 1000 = $1500

so, after 10 years : rick has $1400 and sally has $1500
