Question

Find the value of 6.25*6.25-1.75*1.75/4.5

Answer 1

Answer:

$The \: value \: of \\\frac{6.25\times 6.25-1.75\times 1.75}{4.5}=8$

Step-by-step explanation:

$The \: value \: of \\\frac{6.25\times 6.25-1.75\times 1.75}{4.5}\\=\frac{(6.25)^{2}-(1.75)^{2}}{4.5}\\=\frac{(6.25+1.75)(6.25-1.75)}{4.5}$

/* By algebraic identity:

a²-b² = (a+b)(a-b) */

$=\frac{8\times 4.5}{4.5}\\=8$

Therefore,

$The \: value \: of \\\frac{6.25\times 6.25-1.75\times 1.75}{4.5}=8$
