-----> A<span>ny number at all with a 0 exponent is 1; anything with a -ve exponent means "1 over" i.e. 5^-1 means 1/5, 23^-4 means 1/23^4 etc.
</span>----->A number to the power of zero is always 1
<span>A number to the power of a negative number such as 2^-4 is always the reciprocal to the power of 4 so 2^-4 is in fact (1/2) ^4 = 1/2^4 </span>
<span>3^-3/4 is (1/3)^3/4 </span>
<span>(4/9)^-3/5 is (9/4)^3/5
</span>
--->Any number with a zero exponent is equal to 1. A number n to the -x is equal to 1/(n^x)<span>
To simplify a negative exponent expression , I attached an example it is easier that way :)
Hope that helps.xoxo

Step-by-step explanation:
Answer:
Answer is D.
Step-by-step explanation:
40h is what you start out with since it costs 40 ever hour. then you add the service charge which makes it 40h + 125, and then since the total charge is 1205, that would complete the equation.
Answer:
Final answer is $12696.
Step-by-step explanation:
Given that initial amount P = $28000
Interest rate r = 5.8% = 0.058
Time = 1 year
Then future value is given by :


Similarly calculate future value for 2nd case:
Given that initial amount P = $16000
Interest rate r = 5.8% = 0.058
Time = 1 year
Then future value is given by :


then difference = 29624 - 16928 = 12696
Hence final answer is $12696.
