So the first one is (7x)^(1/2) or square root of 7x minus - 5 square root all squared so
([7x^(1/2)]-[5^(1/2)]) times ([7x^(1/2)]-[5^(1/2)])
or 7x-(35x^(1/2))-5+(35x^(1/2)) or 7x-5
number 2
since 11 is 1/2 of 22 it can be written as
the square root of 3 or 3^(1/2)
Answer:
2x24=3=41
Step-by-step explanation:
Answer:
1. False, 16=8
2. False, 15=243
3. True, 125=125
4. False, 8=9
5. False, 16=64
6. False, 0.0625=2
7. False, 0.0625=0.125
8. True, 64=64
Step-by-step explanation:
Rational zero theorem is all combinations of p(factors of the constant) divided by q(factors of the first coefficient)
factors of 8 are 1, 2, 4, 8
factors of 2 are 1, 2
so all possible rational zeros are all combinations of p/q
+/- 1/1, 1/2, 2/1, 2/2, 4/1, 4/2, 8/1, 8/2
Now there are some repeats in there so you have to leave those out and once we do that we get
+/- 1, 1/2, 2, 4, 8
Remember all those are plus OR minus
Answer:
3.46410162 i
Step-by-step explanation:
The i is for imaginary because you cannot take the square of a negative number. Hope this helps
