my answers
1.d
2. b
pls help me steve or ms sue.
Online, “*” is used to indicate multiplication to avoid confusion with “x” as an unknown.
I agree with your answers.
5^2 * 5^4 = 5^6
3^3 * 3^6 = 3^9
Also, indicate your specific subject in the "School Subject" box, so those with expertise in the area will respond to the question.
pls help me
To solve the given expressions and determine whether they are true or false, we can use the properties of exponents.
1. For expression A, we have 4^3 x 4^4. To simplify, we add the exponents when multiplying the same base, so it becomes 4^(3+4) = 4^7. This means that option A is incorrect since it does not equal 4^12.
2. For expression B, we have 5^2 x 5^3. Again, using the property of multiplying same bases, we add the exponents to get 5^(2+3) = 5^5. So, option B is incorrect since it does not state that it is greater than 5^5.
3. For expression C, we have 3^2 x 3^5. Applying the same property, we add the exponents to get 3^(2+5) = 3^7. Thus, option C is incorrect since it is not equal to 3^10.
4. For expression D, we have 5^2 x 5^4. Following the property, we add the exponents to get 5^(2+4) = 5^6. Therefore, option D is correct since it states that it is less than 5^8.
Based on the above explanations, your answers are correct. Option D is true for the first question, and option B is true for the second question.
