-2x√180x^4y^9
if 180x^4 * y^9 is all under the square root x^4 simplified to x^2 y^9 simplified to y^3 180 simplifies to ... 2 * 2 * 3 * 3 * 5 so that means sqrt(180) simplifies to 36sqrt(5)
answer: -72 * x^3 * y^3 * √5
i think |

If I had it on paper I would help. I just hate the exponents with the "^" sign.
I've already gone through Geometry and I'm in Algebra 2, I could help. Sorry. |

-2x√180x^4y^9
first split up everything
-2x * √180 * √x^4 * √y^9
think what squared goes into 180, do it slow if need be
-2x * √9 * √20 * √x^4 * √y^9
for variables like x and y with exponents, the exponents to the square root gets divided by 2
-2x * 3 * √4 *√5 * √x^4 * √y^8 * √y
simplify
-6x * 2 * √5 * x^2 * y^4 * √y
continue simplifying til you're finished
-12x^3y^4√5y
^final answer^

another way to think of exponents under radicals
√x^4 = x^(4/2) = x^2

| I still don't understand it at all. How would you do 2 ^3√16a^3b^4c^5? |

tinopls, i had 100+% every quarter last year in pre-calc, and ill have at least 100% this quarter in AP calc, im 1 point under 100% after 3 tests, and my latest one will probably be the drop test, and i have probably 5 points of ec from assignments that'll get me over

2^3√16a^3b^4c^5
8 * √16 * √a^3 * √b^4 * √c^5
8 * 4 * a^(3/2) * b^(4/2) * c^(5/2)
16 * a * √a * b^2 * c^2 * √c
16ab^2c^2√ac

| Wait, the 3 is like above the little curve line on the square root. Is that still the answer? |

is it like 2 * 3√(whatever was here)? (2 times the cubed root of -insert things here-) if so, no

| No, its 2 (small space) (the 3 is like an exponent on the outside of the square root) ^3√16a^3b^4c^5. So the final radical looks like 2 ^3√16a^3b^4c^5 |
