The expression which has a value that is less than the base of that expression is (5/6)².
Exponents and powers are ways used to represent very large numbers or very small numbers in a simplified manner.
For example, if we have to show 3 x 3 x 3 x 3 in a simple way, then we can write it as , where 4 is the exponent and 3 is the base.
Given:
Whenever you have positive exponents, bases above 1 will be greater.
and, when the exponent and bases between 0 and 1 will be less after the exponent.
In part (a), (c), and (d) the value is greater.
But in part (b) the value is less than the base of that expression.
Hence, the expression is (5/6)².

The answer is x + 3
Step 1: Expand ( 3x + 3 - 2x )
Step 2: Collect like terms ( (3x - 2x) + 3 )
Step 3: Simplify ( x + 4 )
Let me know if I helped :)
Answer:
see explanation
Step-by-step explanation:
Using the Addition/ Subtraction formulae for cosine
Consider the left side
cos(x - y) - cos(x + y)
= cosxcosy + sinxsiny - (cosxcosy - sinxsiny) ← distribute
= cosxcosy + sinxsiny - cosxcosy + sinxsiny ← collect like terms
= 2sinxsiny = right side ⇒ proven
An accurate description of early Native Americans would be hundreds of Indian peoples, tribes, languages, and ways of life.
Therefore we can conclude that early Native Americans led a harmonious life balancing nature and their ways of life.
Thus option B. is correct answer.
