Answer:
The value of given expression is 1.
Step-by-step explanation:
The given expression is

If a is a real number, then
.
![[\because a^0=1]](https://tex.z-dn.net/?f=%5B%5Cbecause%20a%5E0%3D1%5D)
Using exponent property we get,
![[\because a^{-n}=\frac{1}{a^n}]](https://tex.z-dn.net/?f=%5B%5Cbecause%20a%5E%7B-n%7D%3D%5Cfrac%7B1%7D%7Ba%5En%7D%5D)


Therefore the value of given expression is 1.
Answer:
18 is 72% of 25 which is also known as 28% less of 25
Step-by-step explanation:
18/25=.72
1-.72=.28
.28=28%
C) 93
Q has the reverse digits of P
Q is 39 and P is 93
93 - 39 = 54
Answer:
To solve this inequality you need to get m by itself
3m+10<30 (First subtract 10 from each side)
3m<20 (10-10=0, 30-10=20) (Then divide each side by 3)
m< 20/3 or 6.666666
So your answer is any that is less than 6.66666
Your answer would be 5
5
Hope this helps ;)
