6^2 * 6^(-4) = 6^(-2)\n\nYou can add the exponents (2 and -4) when multiplying by the same base (6). Likewise, you can subtract when dividing.\n\nTo that end, 6^(-2) = 6^0 / 6^2 = 1/36 (since anything to the power of zero is equal to 1).\n\nTherefore your answer is 6^(-2), or 1/36. They are both the same.

An expression is a combination of numbers, operators, grouping symbols (such as brackets and parentheses) and/or free variables and bound variables arranged in a meaningful way which can be evaluated. 5+4 and 1/x+3 are both expressions.\nWhereas an equation is a mathematical statement that sets two expressions equal to each other; 2x-9=3x+17 is an example of an equation.

2x + 28 < with a line under it _ <_   6x\n\nsorry don't know how to add that special character in, but it is only one thing like the +\n between the 28 and 6

I believe it simplifies to n - w.\n\nHere's the expression you wrote: (a-y/w+n * w^2-n^2/y-a).\n\nHere's what I think it should look like:\n\n((a-y)/(w+n)) * ((w^2-n^2)/(y-a))\n\nBecause:\n\n((a-y)/(w+n)) * ((w^2-n^2)/(y-a))\n\n= ((a-y)/(w+n)) * ((w+n)(w-n))/(y-a)\n= ((-1)(y-a)/(w+n)) * ((w+n)(w-n))/(y-a)\n\nThe (w+n)'s cancel out, as do the (y-a)'s, so you're left with this:\n\n= (-1)(w-n)\n= (n-w)
