-3 * sqrt(28a^36 * b^25 * c^36)

When you take the square root of something raised to a power, it's like dividing that power in half. Example sqrt 2^6 = 2^3. Check 2^6 = 64; 2^3 =8 checks.

sqrt(28a^36) = a^18 * sqrt(4*7) = 2a^18(sqrt7)
sqrt(b^25) = b^12.5 or b^12*sqrtb
sqrt(c^36) = c^18

So
-3 * sqrt(28a^36 * b^25 * c^36) =
-6 * a^18 * b^12 * c^18 * sqrt(7b)

this is really confusing, you should put in the carrot top for all of the powers: b^25

you can't solve problems with multiple variables without using creating a matrix, which is calc BC type stuff
