-5^7/-5^2=5^7/5^2= 5^(7-2)=5^5 this is the answer
For the first one we divide every element by sqrt3
we get
q+2/sqrt3 =sqrt5/sqrt3
q=(sqrt5-2)/sqrt3
q=sqrt3*sqrt5-2*sqrt3/3
q=sqrt15-2sqrt3/3
which is the third option
For the second one
sqrt(2y-5) +4=8
first we move the 4 to the right
sqrt(2y-5)=4
we remove the square root by bringing to the power of two
2y-5=16
2y=21
y=21/2
y=10 1/2
third option
The answer is C

Answer:
22222222/100000000
Step-by-step explanation:
To write 0.22222222 as a fraction you have to write 0.22222222 as numerator and put 1 as the denominator. Now you multiply numerator and denominator by 10 as long as you get in numerator the whole number. 0.22222222 = 0.22222222/1 = 2.2222222/10 = 22.222222/100 = 222.22222/1000 = 2222.2222/10000 = 22222.222/100000 = 222222.22/1000000 = 2222222.2/10000000 = 22222222/100000000.
