Exponents: Number Sense Activities

These should be approached without a calculator. A calculator might be used to check solution.

Number Sense Activity 1:

Compare the first five powers of 4 with the first ten powers of 2. Explain the pattern.  Choose various values of m and n such that the following equation is true:


Number Sense Activity 2:

Write three different equations, choosing values for m and n carefully such that the equation


is true. Check your equations with a calculator.

Number Sense Activity 3:

Which one of the following is true:

    \[\frac{4^6}{5^6}&\geq \frac{4^7}{5^7}\]

    \[\frac{4^6}{5^6}&= \frac{4^7}{5^7}\]

    \[\frac{4^6}{5^6}&\leq \frac{4^7}{5^7}?\]

Number Sense Activity 4:

Which is bigger;




Number Sense Activity 5

Put the values in the correct place in the table

    \[ \boxed{\frac{2^3}{3^3};\quad \frac{2^5}{2^{10}}; \quad \frac{10^6}{10^7}; \quad \frac{8}{1.9^3}; \quad \frac{3.2^3}{27} } \]
