Which expression is equivalent to 7square root x^2/5 square root y^3? assume y≠0

A= (x^2/7)(y^-3/5)

Step-by-step explanation:

7√x^2 / 5√y^3

7√x^2

=(x^2)1/7

=x^2/7

5√y^3

=(y^3)1/5

=y^3/5

Substitute into the expression

(x^2/7) / (y^3/5)

=(x^2/7)(y^-3/5)

it’s supposed to be -4+45=41

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
