Lets solve this problem:(5x^2)(5x^2)^2
so first of all you would do the () first
so lets do the first one first. 5x^2 = 5*5 wich would equal 25
so the () by each other means multiply
so now its: 25*(5x^2)^2
5x^2= 5*5=25
now its: 25*25^2
do 25^2 first: 25 * 25 =625
625*25
625*25=15,625
your answer 15,625
Given, the signing bonus of Jayden = $600.
Jayden makes $26 in an hour.
Jayden works for x hours.
For 1 hour he makes = $26
So for x hours he will make = $
= $
So the total pay of Jayden = The sum of the signing bonus and the total pay for x hours.
The total pay of Jayden = $(
)
Given, jayden's total pay = y dollars.
So we can write the equation as 
we have got the required equation 
Answer is z=36
First find the ratio of the similar sides
55/44 = 1.25 ratio
Divide 45 by the ratio to find z
45/1.25 = 36
