Which of the following is an equivalent expression to 7/(-5.3) to the exponent of zero+ 4x9 when applying the zero power rule

7/1+4x9
7/5.3+4x9
7/0+4x9
7/5.3^0+36

The zero power rule states that any number (except for 0) raised to the power of zero is equal to 1.

Therefore, when applying the zero power rule to 7/(-5.3)^0 + 4x9, we have:

7/1 + 4x9

This simplifies to:

7 + 36

The equivalent expression is:

7 + 36 = 43
