To evaluate the expression \( \frac{7}{(-5.3)^0} + 4.9 \), we first apply the zero power rule, which states that any non-zero number raised to the power of 0 is equal to 1.
Thus, we have:
\[ (-5.3)^0 = 1 \]
Now substituting this back into the expression gives us:
\[ \frac{7}{(-5.3)^0} + 4.9 = \frac{7}{1} + 4.9 = 7 + 4.9 \]
Now we can simplify:
\[ 7 + 4.9 = 11.9 \]
So, the equivalent expression is:
\[ 11.9 \]
