Which expression is equivalent to 4x^2 to the square root of 5x^4 • 3 to the square root of 5x^8 if x ≠ 0

Step-by-step explanation:

Lets simplify the square roots:

Lets multiply:

           Combine like terms

               Combine like terms, simplify

                          Simplify

-Chetan K

the entire expression should be subtracted from 30. to subtract the quantity, distribute the negative sign, which changes the signs on the terms. so, the –2 changes to positive and gets added to 30 instead of subtracted from it.
