Question

What is the 1st term when −5z2 + 7z4 + 11z − 8z3 is arranged in descending order

Answer 1

7z^4

Explanation:

Look at the exponent power. The largest exponent goes first, the second largest goes second (etc.). The number/variable with no exponent will always go last.

Answer 2

descending order...largest to smallest
the largest one is the one with the biggest exponent
so the first term is : 7z^4
