Answer:
AECG
Step-by-step explanation:
1
sqrt(49) = 7
sqrt(a^2) = a
sqrt(b^2) = b
For every two variables you can take one out from under the root sign and thorough the other one away.
Answer: E
2
sqrt(36) = 6
sqrt(a^2) = a See comment for 1.
b must be left where it is. There is only 1 of them.
6asqrt(b)
Answer: A
3. sqrt(25) = 5
sqrt(b^2) = b
a must be left alone. There's only 1 of them.
5b sqrt(a)
answer: C
4
sqrt(81 a b)
sqrt(81) = 9
The variables must be left alone. There's only1 of them
9 sqrt(ab)
Answer G
No
it is irrational for that reason - it goes on without bound
Answer is B
-0.6- (-0.4)= -0.6+0.4= -0.2
Answer:
When ever you can’t solve it it considered false like 4 - 12
Step-by-step explanation:
10/19. 40/4=10, and 56/4=19. therefore the answer is 10/19.
