Need help on a math question: Index Form

Simplify the following, leaving your answer in index form :
a- 2 to the power of 5 x 2 to the power of negative 3
b- 3 to the power of seven ÷ 3 to the power of 3
c- 4 to the power of 9 x 4 to the power of 6 ÷ 4 to the power of negative 3
d- (5 to the power of 2) to the power of 3
multiplying indexes with same base-> ADD POWERS
dividing indexes with same base-> SUBTRACT POWERS
brackets (like your last one)-> MULTIPLY POWERS

example: 2^3 * 2^-5
same base of 2
3+-5 = -2
therefore the answer is 2^-2

fyi ^ means to the power of

pm me if you need more help, but this should sort you out
