Step-by-step explanation:
2^3 X 3^-4 X 5^2 / (2x5)^2 X 2 X 3^2 X 3^-6
I will simply the expression on the RHS if the bracket first
2^2 X 5^2 X 2 X 3^2 X 3^-6
= 2^3 X 3^-4 X 5^2
So, putting them together
Both sides have th same expression
They cancel out each other

Answer: 25x² - 64
<u>Step-by-step explanation:</u>
(5x + 8)(5x - 8)
= 5x(5x - 8) + 8(5x - 8)
= 25x² - 40x + 40x - 64
= 25x² + 0x - 64
= 
NOTE: descending powers means the biggest exponent goes first, then the next biggest exponent, etc.
For example: x⁴ then x³ then x² then x then the number (which is actually x⁰)

7 girls on a bus, each has two legs. 7 * 2 = 14.
Each girl has 7 backpacks. So 7 * 7 = 49.
49 * 7 = 343 cats in total
343 * 4 = 1,372 cat legs.
343 * 7 = 2401 small cats
2401 * 4 = 9,604 cat legs
14 + 1,372 + 2,401, + 9,604 = 10,990 legs in total
