Simplify the expression. \( \frac{9(6-4)^{5}-6 \cdot 4+3 \cdot 7}{4^{3}+9^{2}} \) \( \frac{9(6-4)^{5}-6 \cdot 4+3 \cdot 7}{4^{3}+9^{2}}=\square \) (Round to the nearest thousandth.)

e) \( \sqrt{1+\frac{9}{16}}= \)

Simplify and add or subtract wherever possible. \( 2 \sqrt{32}-5 \sqrt{18}-2 \sqrt{27} \) The simplified form is (Type an exact answer, using radicals as needed.)

3). \( 9 \sqrt{12}+5 \sqrt{32}-\sqrt{72} \)

Simplify the expression. \( \frac{2(5-4)^{3}-5 \cdot 9+7 \cdot 8}{9^{2}+8^{3}} \) \( \frac{2(5-4)^{3}-5 \cdot 9+7 \cdot 8}{9^{2}+8^{3}}=0.021922 \) (Round to the nearest thousandth.)

Simplify the expression. \( \frac{2(5-4)^{3}-5 \cdot 9+7 \cdot 8}{9^{2}+8^{3}} \) \( \frac{2(5-4)^{3}-5 \cdot 9+7 \cdot 8}{9^{2}+8^{3}}=\square \) (Round to the nearest thousandth.)
