1. 11m^4√ (8m^5n^9) x 4m^2√ (8m^4n^7)

2. Simplest terms indext^3√ (16m^27)

1. Assuming it is 11*(m^4)*√(8*(m^5)*(n^9)) x 4*(m^2)*√(8*(m^4)*(m^7))
The answer is 352*(m^10)*(n^8)*√m

2. What is indext???

Ah so you meant (√(16*(m^27)))^3
Or rather 64*(m^39)*((√m)^3)

11m^4√ (8m^5n^9) * 4m^2√ (8m^4n^7)
= 44m^6√(64m^9n^16)
= 352 m^10n^8√m

∛(16m^27)
= ∛(2^3 * 2 * (m^9)^3)
= 2m^9∛2
