Answer: x⁴y²⁰
Step-by-step explanation: Distribute the exponent ⁴ over the parentheses
(x y⁴)⁴ becomes x⁴y¹⁶ (multiply exponents)
then take the 4th root of y¹⁶ (divide the exponent of the radicand by the index) ⁴√y¹⁶ becomes y⁴
Then multiply the factors. Add exponents
x⁴y¹⁶ * y⁴ becomes x⁴y²⁰
Answer:
I think it's x=-12 for the buttom one
Step-by-step explanation:
I think when you get open equations like these you would asume 1 is there so rewrite it as 2x + 25 = 1
so take the 25 away from 1. to do that we need to do the opisite of +
2x + 25 = 1
1 - 25 = -24
rewrite
2x = -24
take the 2 away. oppisite of mulitplication is division. so divide 2 by -24
-24 divided by 2 = -12
Hope this helps! Please mark as brainliest! Thanks! If you need me to solve the top one too, I'll do it! Just comment bellow. :D

Step-by-step explanation:
Answer:
Total weight of gravel on the roof = 
Step-by-step Explanation:
The area Adams planned to cover with gravel can be divided into 3 rectangles as shown in the diagram attached.
We would have 3 rectangles. See the attachment below to check out how we arrive at the dimensions of the 3 rectangles.
Area of rectangle = L*W
Area to be covered by gravel = area of rectangle 1 + area of rectangle 2 + area of rectangle 3
Area to be covered with gravel = 
Total weight of gravel on the roof = 12 pounds per square foot multiplied by total area of the roof to be covered =
