I think n is 9 hope i helped
8 times since 4x4x4=64 and 8x8x8=512
so 512/64 equals 8 so it's 8 times greater

Answer: 
Step-by-step explanation:
25 = 5*5 or -5 * -5
yes, that is correct. However, you forgot another property of roots. Roots are simply exponential fractions.
![\sqrt[n]{x^m}=x^\frac{m}{n}](https://tex.z-dn.net/?f=%5Csqrt%5Bn%5D%7Bx%5Em%7D%3Dx%5E%5Cfrac%7Bm%7D%7Bn%7D)
Therefore,
can also be rewritten as:
. Notice that it cannot be -25 because that would be a negative square root which will give us an imaginary number.
(x)(10+x)=96


(x-6)(x+16)=0
x=6,-16
negative can't be an answer this the answer is 6+10= 16 ft
