What is the final product? ^5sqrt4x^2 ^5sqrt4x^2
AnnyKZ [126]
For this case we have the following expression:
 ^ 5sqrt4x ^ 2 ^ 5sqrt4x ^ 2
 Rewriting the expression we have:
 ((4x ^ 2) ^ (1/5)) ((4x ^ 2) ^ (1/5))
 For power properties we have:
 (4x ^ 2) ^ (1/5 + 1/5)
 (4x ^ 2) ^ (2/5)
 Rewriting we have:
 (16x ^ 4) ^ (1/5)
 ^ 5sqrt16x ^ 4
 Answer:
 
^5sqrt16x^4

Solve for s:
6 s^2 = 294
Divide both sides by 6:
s^2 = 49
Take the square root of both sides:
