Anumber to the 11th power divided by the same number to the 8th power equals 216. what is the number?

Let "a number" be signified by x.
"A number" to the 11th power,
x^11

divided by "the same number" to the 8th power,
x^11 / x^8

equals 216,
x^11 / x^8 = 216

Apply your exponent rule, division to subtraction,
x^(11-8) = 216
x^3 = 216

"the number" is being raised to the third power.
To isolate our number, x, we'll apply the inverse of raising to a power:
Taking a third root (or applying a 1/3 power).



and simplify,

x= 6

The answer is 25uthere is no v in the question

At a constant it will take one hour to travel 32 mi.at that speed it will take 1/2 hr to travel the remaining 16 mi.it will take 1+1/2 hr to travel the 48mi @ 32mph.so 1 hr = 60 min& 1/2 hr = 30 min1+1/2 hr = 90 min.there are 60s in each 90 × 60 = 3600 seconds.the real question seriously is he why are they driving so slow? ! lol.
