Answer:
StartFraction 6 Over 5 x Superscript 10 Baseline EndFraction
Step-by-step explanation:
Apparently you want to simplify ...
The applicable rules of exponents are ...
(a^b)(a^c) = a^(b+c)
1/a^b = a^-b
(a^b)^c = a^(bc)
__
So the expression simplifies as ...
Answer:
40/7
Step-by-step explanation:
14x - 71 = 9
14x=80
x=80/14
x=40/7
Answer:
19.64
the permieter is 5 so 5/2=2.5 2.5x2.5=6.25 6.25x3.14=19.64
The length of the race is 5 kilometers.
5 kilometers equals 5000 meters.
Since Lana's avarege step length is about 0.5 meters, we need to divide 5000 by 0.5
Hence, Lana needs to take about
10000 steps.
B is the irrational. C & D are rational as they can be written in a ratio, aka a simple fraction. A is rational as it simplifies to +/-2, a whole number.
