Questions and Answers
  • 1. 

    Simplify: (n5)(n2)(m3)(m4

    Correct Answer
    B.
    Explanation
    The given expression can be simplified by multiplying the coefficients and adding the exponents of the variables with the same base. In this case, the expression can be simplified to n^7 * m^7, where n has an exponent of 7 and m has an exponent of 7.

    • C.

      10

    • D.

      -10

    Correct Answer
    B. -10
    Explanation
    The given expression can be simplified by multiplying the coefficients and adding the exponents of the variables. In this case, (5d3)(-2d2) simplifies to -10d^5, where the coefficient is -10 and the exponent of the variable d is 5. Therefore, the answer is -10.

  • 3. 

    Simplify: (m4)2

    Correct Answer
    B.
    Explanation
    To simplify (m^4)^2, we need to apply the exponent rule which states that when raising a power to a power, we multiply the exponents. In this case, we have m^4 raised to the power of 2. Multiplying the exponents 4 and 2 gives us m^8. Therefore, the simplified form of (m^4)^2 is m^8.

    Rate this question:

  • 4. 

    Simplify: 5x2(52x3)

    Correct Answer
    C.
    Explanation
    The expression can be simplified using the order of operations, which states that multiplication should be done before addition or subtraction. First, we solve the multiplication within the parentheses: 52x3 = 156. Then, we multiply this result by 5x2 = 10. Therefore, the simplified expression is 10(156) = 1560.
