A negative exponent means the reciprocal of the positive exponent → y^-8 = 1/(y^8) = 1/(y×y×y×y×y×y×y×y)
It is y^2 or y squared
(y^2 - 4) / (y + 2) = [(y -2)(y+2)]/(y+2) = y-2
2x / (y-2) + 2x / (2-y)First get a common denominator: (y-2) (2-y)Then you have:2x(2-y) / (y-2)(2-y) + 2x(y-2) / (y-2)(2-y), summing and simplifying, you get:(4x-4) / (y-2)(2-y)
(x2 - y2)/(x - y) = (x + y)(x - y)/(x - y) = x + y

means y ????????
(y * x) - y = y * (x - 1)
GCF(Y, Y) = Y.
y = sin(x+y) cos( x + y )[(1 + y')] = y' cos(x + y ) + y'cos(x + y ) = y' y'-y'cos( x+ y) = cos( x + y ) y'[1-cos(x+y)]= cos(x+y) y'= [cos(x+y)]/ [1-cos(x+y)]
y/5
GCF(Y, Y) = Y.
X + Y⁶X + Y * Y * Y * Y * Y * Y
Y squared (Y^2)
The answer is 37478482993
y^2 X y^3 = y^(2 + 3) = y^5 You can only do this if the coefficient 'y' is the same for both terms. Remember y^2 = y X y y^3 = y X y X y Hence y^2 X y^3 = y X y X y X y X y = y^5 Similarly for division/subtraction y^3 / y^2 = y^(3 - 2 ) = y^1 = y The power of '1' is trivial and not normally shown. NB You CANNOT do z^2 X y^3 by adding the indices. z^2 X y^3 is (z^2)*(y^3)
if Y ≠ 0 → Y ÷ Y = 1 If Y = 0, Y ÷ Y = any and every number (it is the basis of calculus).
