Question

using suitable identity , find the value of (0.98x1.02).​

Answer 1

Answer:

0.9996

Step-by-step explanation:

$(0.98 \times 1.02)$

$= (1 - 0.02) \times (1 + 0.02)$

Using identity

$(x + y)(x - y) = {x}^{2} - {y}^{2}$

Therefore,

${(1)}^{2} - {(0.02)}^{2}$

$= 1 - 0.0004$

$= 0.9996$
