Question

the value of (0.9) power 2 minus (0.1) power 2 is dash​

Answer 1

Answer:

The value of $(0.9)^{2}-(0.1)^{2}$ is 0.8.

Step-by-step explanation:

The expression is:  $(0.9)^{2}-(0.1)^{2}$

The formula of (a² - b²) is (a + b)(a - b).

Use this relation to compute the value of the expression as follows:

$(0.9)^{2}-(0.1)^{2} = (0.9 +0.1)(0.9-0.1)=1\times0.8=0.8$

Thus, the value of $(0.9)^{2}-(0.1)^{2}$ is 0.8.
