Which of the following is an equivalent expression to 7/(-5.3)^0 + 4.9 when applying the zero power rule

1 answer

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:

\[ 11.9 \]
