Question

the value of(0.68)2-(0.32)2 is​

Answer 1

SOLUTION

TO DETERMINE

The value of

$\sf{ {(0.68)}^{2} - {(0.32)}^{2} }$

FORMULA TO BE IMPLEMENTED

We are aware of the identity that

$\sf{ {a}^{2} - {b}^{2} = (a + b)(a - b) }$

EVALUATION

$\sf{ {(0.68)}^{2} - {(0.32)}^{2} }$

$\sf{ = (0.68 + 0.32)(0.68 - 0.32)} \: \: (\: using \: above \: identity)$

$\sf{ = 1.00 \times 0.36}$

$= 0.36$

FINAL ANSWER

$\boxed{ \: \sf{ {(0.68)}^{2} - {(0.32)}^{2} } = 0.36 \: \: }$
