Answer 2

The value of 38 square - 22 square upon 16 using suitable identity is 60

Solution:

Given that,

We have to find value of :

$\frac{38^2 - 22^2 }{16}$

Use the following identity

$a^2 - b^2 = (a+b)(a - b)$

Therefore,

$38^2 - 22^2 = (38 + 22)(38 - 22)\\\\38^2 - 22^2 = (60)(16)$

Thus the given expression becomes,

$\frac{38^2 - 22^2 }{16} = \frac{ 60 \times 16 }{16}\\\\Simplify\\\\\frac{38^2 - 22^2 }{16} =60$

Thus the value of given expression is 60
