X*x3=x1.5*x1.5
- A.
True
- B.
False
Correct Answer
B. FalseExplanation
The equation x*x3 = x1.5*x1.5 is not true. When we multiply x by x3, we get x^4. When we multiply x1.5 by x1.5, we get 2.25x^2. These two expressions are not equal, so the statement is false.Rate this question:

Correct Answer
Power of a power
Product of powersExplanation
When simplifying the expression (32*36)5, we can use the properties of powers. The expression can be rewritten as (32^5)*(36^5). According to the power of a power property, we can multiply the exponents, resulting in 32^(5*5)*36^(5*5). Using the product of powers property, we can simplify this further to 32^25*36^25. Therefore, the correct answer is Power of a power, Product of powers.Rate this question:
