Answer: C
Step-by-step explanation:
Simplify the expression to 2^1/4
Now transform the expression using a^m/n = n root a raised to a power of m.
And that's how you get your answer.
Answer:
(69)(3)−8
=
15
199≠15
False
Step-by-step explanation:
hope it helps, 69(3) is already bigger than 15, then -8 makes it 199, which is definitely not equal to 15.
Hi there
-2 ≥ 4p + 6 + 4
-2 ≥ 4p + 10
4p +10 ≤ -2
Now subtract 10 form both sides
4p + 10 - 10 ≤ -2 - 10
4p ≤ -12
Divide by 4
4p/4 ≤ -12/4
p ≤ -3
I hope that's help:)
