Answer:
Step-by-step explanation:
a. 16b^2c^12-0.25 can be rewritten as follows because it is the difference of two squares:
(4bc^6 - .5)(4bc^6 + .5)
b. 81x^6y^2-0.36a^2
is the difference of two squares, just like (a) (above); its factors are:
(9x^3y - 0.6a)(9x^3y + 0.6a)
The aquarium tank volume is greater by a factor of 8³ = 512.
a) 5y²
5 divided by 1 is still 5
y^5/y^3 subtract the exponents since the base is the same
