The rule for multiplying similar bases with exponents:
(a^b)(a^c)=a^(b+c)
In this case we have:
(5^-2)(5^-1)
5^(-2-1)
5^(-3)
The rule for negative exponents:
a^(-b)=1/(a^b)
So in this case:
5^(-3) is equal to
1/(5^3)
1/125
The answer is 6x^2+11x-35
Answer:
3.26 hours
Step-by-step explanation:
speed = distance / time
595 = 1940 / t
t = 1940 / 595 = 3.26 hours
