I think the answer to your question would be B
The result of the given exponential expression is given as 1/8, 3^2, 1/5 and 5^-2
<h3>Properties of exponents</h3>
Some of the properties of exponents are expressed as shown below;
1) a^-n = 1/a^n
In order to answer the given questions, we will use the following properties above;
3^-4 = 1/3^4 where a is equivalent to 3 and n is equivalent to 4
Similarly;
1/2^3 = 2^-3 = 1/8
For the expression 1/3^-2
1/3^-2 = 1/(1/3^2)
1/3^-2 = 3^2
For the expression 5^-1
5^-1 = 1/5^1
5^-1 = 1/5
Also for 1/5^2
1/5^2 = 1/25 = 5^-2
Hence the result of the given exponential expression is given as 1/8, 3^2, 1/5 and 5^-2

Answer:
(3x+2)(x+2)
Step-by-step explanation:
1 Split the second term in 3{x}^{2}+8x+43x
2
+8x+4 into two terms.
3{x}^{2}+6x+2x+43x
2
+6x+2x+4
2 Factor out common terms in the first two terms, then in the last two terms.
3x(x+2)+2(x+2)3x(x+2)+2(x+2)
3 Factor out the common term x+2x+2.
6.35 is 2 standard deviations below the mean of 7.13, so the empirical rule tells you 2.5% are in the lower tail of the distribution.
_____
The empirical rule says 95% are within 2 standard deviations of the mean, so 5% are outside that range. Those 5% are evenly split between the upper and lower tails of the distribution, so 5%/2 = 2.5% are in the lower tail, below -2 standard deviations.
The value 6.35 is 0.78 = 2×0.39 less than the mean of 7.13.
