![(\sqrt[6]{x^5} )^7](https://tex.z-dn.net/?f=%28%5Csqrt%5B6%5D%7Bx%5E5%7D%20%29%5E7)
First step is we convert the sixth root to a 1/6 power,

In general when we have a power raised to a power we get to multiply the exponents,

That's our answer.
Answer: 1.467
Step-by-step explanation:
Formula of Margin of Error for (n<30):-

Given : Sample size : n= 22
Level of confidence = 0.90
Significance level : 
By using the t-distribution table ,
Critical value : 
Standard deviation: 
Then, we have

Hence, the margin of error for the confidence interval for the population mean with a 90% confidence level =1.467
Answer: Square root of x+3
Step-by-step explanation:
Insert the denominator to 3
Answer:
42
Step-by-step explanation:
168 factors into
2•2•2•3•7
two of the 2's make a perfect square
(2•2)•2•3•7
2²•2•3•7
as none of the product of the remaining factors makes a perfect square
2•3 = 6, 2•7 = 14, 3•7 = 21
we need to multiply the remaining factors together to find another perfect square
2²•(2•3•7)²
2•3•7 = 42
42(168) = 7056 = 84²
