Any non-zero number raised to the power of 0 is equal to 1. Therefore:
\[
\left(\frac{3}{5}\right)^{0} = 1
\]
Now multiply by 3:
\[
3 \times 1 = 3
\]
Step 2: Evaluate \( (-9)^{10} \)
When a negative number is raised to an even power, the result is positive. Therefore:
\[
(-9)^{10} = 9^{10}
\]
Now calculate \( 9^{10} \):
\[
9^{10} = 3486784401
\]
