BAHAHA I SAW MY NAME AND GOT SO SCARED
1st problem: 6/y^4
first, we express it with positive exponents.
6 x 1/y^4
then, we just calculate it.
6/y^4
2nd problem: (1/64)a^7 (the a^7 isn't just on the bottom part, it goes in the front of the fraction)
first, i expressed it with a positive exponent.
1/8^2 x a^7
then, i evaluated that.
(1/64)a^7
