Answer:
The correct option is C. 5
Therefore,

Step-by-step explanation:
Simplify

Solution:
Using Identity

So in the given expression

Therefore,

Therefore,

Answer:
r = 3.
Step-by-step explanation:
16 = 10 + √(3r + 27)
√(3r + 27) = 6
Square both sides:
3r + 27 = 36
3r = 36 - 27 = 9
r = 3.
Check the result:
Left side of the equation = 16
Right side = 10 + √(9 + 27)
= 10 + √36 = 16
Answer:
2 11/12 mixed number
Step-by-step explanation:
Answer:
--- 1 over 5 squared
Step-by-step explanation:
When multiplying terms with a common base, you just add the exponents:

That's true even when you don't have any exponents.


A negative exponent isn't fully simplified, so there's another rule to use:

That is '1 over x to the y' if it's too small to read.
