Answer:
okay the first questions answer is ,c,is true and rest of them are false
Answer:
The answer is 1/9 ⇒ the second answer
Step-by-step explanation:
* In the exponential functions we have some rules
(1) b^(-m) = 1/(b^m) (for all nonzero real numbers b)
- If we have negative power we reciprocal the base
to get positive power
(2) (b^m)^n = b^(mn)
- If we have power over power we multiply them
* In our problem: 
- At first change 27 to b^n
∵ 27 = 3 × 3 × 3 = 3³
∴ 
* Lets use rule (2)
∴
⇒ 3 × -2/3 = -2
* Use rule (1)
∴
⇒ reciprocal the fraction to change the sig of the power
* The answer is 1/9

Step-by-step explanation:
What do you have to do solve it or what
Answer:
Hence two consecutive even integers are 14 and 16
Step-by-step explanation:
Let x and x+2 be the two consecutive even integers
Then according to the given statement in the question
8x = 7(x+2)
<u>Distributive property </u>
8x=7x+14
<u>Subtraction Property of Equality</u>
8x-7x = 14+7x-7x
<u>Simplifying</u>
x = 14
So the first integer is 14 and second is:
x+2 = 14+2 = 16
Hence two consecutive even integers are 14 and 16 ..
