Here are the solutions for the problems.

: Percentage Calculation
The problem asks to calculate the percentage change.

(4000−3605)3605×100%\frac{(4000 - 3605)}{3605} \times 100\%
  1. Calculate the difference in the numerator.

    4000−3605=3954000 - 3605 = 395
  2. Substitute the difference into the expression.

    3953605×100%\frac{395}{3605} \times 100\%
  3. Perform the division and multiply by 100.

    3953605≈0.10957\frac{395}{3605} \approx 0.10957 0.10957×100%≈10.957%0.10957 \times 100\% \approx 10.957\%

    Rounding to two decimal places:

    ≈10.96%\approx \boxed{10.96\%}

    : Simplify x5×x3÷x2x^5 \times x^3 \div x^2
    This problem involves simplifying an expression with exponents.

  4. Apply the rule for multiplying exponents with the same base (am×an=am+na^m \times a^n = a^{m+n}).

    x5×x3=x(5+3)=x8x^5 \times x^3 = x^{(5+3)} = x^8
  5. Apply the rule for dividing exponents with the same base (am÷an=am−na^m \div a^n = a^{m-n}).

    x8÷x2=x(8−2)=x6x^8 \div x^2 = x^{(8-2)} = x^6

    The simplified expression is:

    x6\boxed{x^6}
