4y3(4+5y)Improved Answer:-16y3/20y4 = 4/5y
16y-9y3 = 0 y*(16-9y2) = 0 y*(4-3y)*(4+3y) = 0 So y = 0 or (4-3y) = 0 or (4+3y) = 0 ie y = 0 or y = 4/3 or y = -4/3
A negative exponent is the same as 1/(the positive exponent). For example, 2^3 is (2*2*2) = 8. 2^(-3) is 1/(2*2*2) = 1/8. So, just calculate the positive exponent version, and put it under 1.
That depends what you want to solve. In many cases, it helps to remember the basic definition: for example, x ^ (-3) = 1 / x ^ 3. (Using the symbol "^" for powers.)
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?

When you have a negative exponent (for example 3^-3) you could make the recipricol of the number. So, this would be 1/3^3. Then all that you would have to do is solve for the exponent ( so in this case the answer would be 1/27)
16y-9y3 = 0 y*(16-9y2) = 0 y*(4-3y)*(4+3y) = 0 So y = 0 or (4-3y) = 0 or (4+3y) = 0 ie y = 0 or y = 4/3 or y = -4/3
6xy/16y = 3x/8 (as long as y≠0) = 3/8x
A negative exponent is the same as 1/(the positive exponent). For example, 2^3 is (2*2*2) = 8. 2^(-3) is 1/(2*2*2) = 1/8. So, just calculate the positive exponent version, and put it under 1.
To solve this problem, we first need to establish the relationship between x, y, and z. From the given information, we have 15x = 20y and 16y = 10z. To find the relationship between x and z, we can substitute y from the first equation into the second equation. By doing this, we get 16(15/20)x = 10z, which simplifies to 12x = 10z. Therefore, 6x would equal 5z.

the -3 is multiplied by itself 5 times, so the exponent is 5: (-3)×(-3)×(-3)×(-3)×(-3) = (-3)^5
you get an exponent when you multiply EXAMPLE 10x10x10=1000 that is an exponent NO DONT THINK THAT IF THE EXPONENT IS 3 YOU MULTIPLY IT BY 3 NO WAY JOSE
A negative exponent is simply the reciprocal of the positive exponent. So simply remove the negative sign and find the reciprocal. Thus, for example, 5-3 = 1/53 = 1/125
