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:

- 4.
You can simplify this expression (32*36)5 by using the ? properties.
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:

X8+x3=x11
- A.
True
- B.
False
Correct Answer
B. FalseExplanation
The given equation is x8+x3=x11. This equation is not mathematically correct as it combines the variables with numbers in a non-standard way. In a typical mathematical equation, the variables and numbers are separated by mathematical operations such as addition, subtraction, multiplication, or division. In this case, the equation is not properly formed, hence the answer is False.Rate this question:
