Question

Find the numerical equivalent of 3 9⋅3 −5

Answer 1

Its 3 to the power of -5

Answer 2

To evaluate the expression \( 39 \cdot 3 - 5 \), we first perform the multiplication:

\[
39 \cdot 3 = 117
\]

Now, we subtract 5 from 117:

\[
117 - 5 = 112
\]

So, the numerical equivalent of the expression \( 39 \cdot 3 - 5 \) is:

\[
\boxed{112}
\]

Answer 3

Thank you for the clarification. If you want to evaluate the expression \( 3^9 \cdot 3^{-5} \), we can simplify it using the properties of exponents.

Recall that when multiplying two powers with the same base, you add the exponents:

\[
3^9 \cdot 3^{-5} = 3^{9 + (-5)} = 3^{9 - 5} = 3^4
\]

Now, we can calculate \( 3^4 \):

\[
3^4 = 3 \times 3 \times 3 \times 3 = 81
\]

So, the numerical equivalent of \( 3^9 \cdot 3^{-5} \) is:

\[
\boxed{81}
\]
