the last one lol- thats just how it works
I think it’s 2 but I’m not sure
Doubling the linear dimensions (side lengths) of any figure doubles its perimeter and quadruples (x 4) its area. If its a 3-D (solid) figure, its volume multiplies by 8 .
Because its not quite clear if the 5 is negative you might want to try once with a positive and once with it negative. anyway, when you only have multiplication like this, so no addition or subtraction, you can "distribute"the exponent on the outside of the parenthesis. so the first two terms become 8^(-2/3)(w^7)^(-2/3) hopefully you can figure out the rest. from here, with w if you have something to an exponent which is also to an exponent, you can multiply the exponents. so that's 7*(-2/3) which is-14/3. let me know if you have trouble with fraction multiplication. now negative exponents have something special about them. if you have a negative exponent you can write it as one over that term with a positive exponent. so the first term becomes 1/(8^(2/3)) which is 1/4.
