Calculate or simplify the expression $$ 2.5^{2}(5^{3}+4.5^{2}+1) $$.
Calculate the value by following steps:
- step0: Calculate:
  $$2.5^{2}\left(5^{3}+4.5^{2}+1ight)$$
- step1: Convert the expressions:
  $$2.5^{2}\left(5^{3}+\left(\frac{9}{2}ight)^{2}+1ight)$$
- step2: Add the numbers:
  $$2.5^{2}	imes \frac{585}{4}$$
- step3: Convert the expressions:
  $$\left(\frac{5}{2}ight)^{2}	imes \frac{585}{4}$$
- step4: Evaluate the power:
  $$\frac{5^{2}}{2^{2}}	imes \frac{585}{4}$$
- step5: Multiply the fractions:
  $$\frac{5^{2}	imes 585}{2^{2}	imes 4}$$
- step6: Multiply:
  $$\frac{14625}{2^{4}}$$
- step7: Evaluate the power:
  $$\frac{14625}{16}$$
The simplified form of $$2.5^{2}(5^{3}+4.5^{2}+1)$$ is $$\frac{14625}{16}$$ or $$914\frac{1}{16}$$ or $$914.0625$$.
