Part 1) What is the ratio between the amount of money contributed by Anna and the amount contributed by her mother?
Let
x -----> the amount of money contributed by Anna
y ----> the amount of money contributed by her mother
we know that
Looking at the table

so
Answer:
Option C
Step-by-step explanation:
(7x^3y^3)^2
= (7)^2 * (x^3)^2 * (y^3)^2
= 49 * x^(3*2) * y^(3*2)
= 49x^6y^6
You have to distribute the terms in "7x^3 * y^3" each to the power of 2
(7)^2 * (x^3)^2 * (y^3)^2
Now you can apply the rule "(x^a)^b = x^a*b" and further simplify the expression
