An exponent means "this many times." So, 4 cubed (to the power of 3; a 3 exponent.) is 4 NOT times 3, but 3 TIMES. So it is 4x4x4(=64). Or, 5 to the power of 5 is 5 times itself 5 times, so, 5x5x5x5x5(=3,125). 3 to the power of 9 is 3 times itself 9 times. Basically, the exponent tells how many times you multiply the number by itself. Does that help?
the -3 is multiplied by itself 5 times, so the exponent is 5: (-3)×(-3)×(-3)×(-3)×(-3) = (-3)^5
(-3)4 = 81
No. An exponent is the degree to which a number is multiplied by itself. For example in 23 the 3 is the exponent. 23 is equal to 2x2x2.
If you mean ' "When" do you add exponents? ' then the answer is when the same base of equal or different exponents is multiplied. in other words, when you hav "3 exponent 3 times 4 exponent 5 " you can't add the exponents because the bases (3 and 4) aren't the same.

3^5*4^5 = (3*4)^5 = 12^5
The base and exponent form a pair. You can chose any positive base and that will determine the exponent.243 = 49^1.5 that is base = 49, exponent = 1.5)or 243 = 10^2.5353 (approx) or 243 = 7^3.
The simplified fraction 3/4 is equal to 0.75.
