You have to distribute the exponent of 4 to the whole equation.
so step one is to distribute to the 3
3^4= 81
then we have to distribute to the x
x^4
then to the 2
2^4= 16
81 * x^4 * 16
* = multiplication sign
Answer: d. 1.3333
Step-by-step explanation:
We know that the standard error of a sampling distribution is given by :-
, where
= Population standard deviation.
n= Sample size.
AS per given , we have
n=81
Then, the standard error of a sampling distribution with a population standard deviation of 12 and the sample size of 81 will be :-

Hence, the standard error of a sampling distribution with a population standard deviation of 12 and the sample size of 81 is 1.3333.
Thus the correct answer is d. 1.3333 .
Answer:
3x^7 / y
Step-by-step explanation:
√63x^15y^9/√7xy^11
= √ [(63/7) x^(15-1) y^(9-11)
= √9x^14y^-2
= √9x^14 / y^2
= 3x^7 / y
Answer:
1000 times
Step-by-step explanation:
Place value of 8 in 89.7 = 80
Place value of 8 in 0.08= 0.08 (8 hundredths)

Thus, the digit 8 in 89.7 is 1000 times bigger than the digit 8 in 0.08.
