Evaluate by using identity(a) 0.63 X 0.63 - 0.37 X 0.37
Added by Austin W.
Step 1
63 X 0.63 - 0.37 X 0.37 = (0.63)^2 - (0.37)^2 Now, we can use the identity: a^2 - b^2 = (a + b)(a - b) to simplify the expression further. In this case, we have: (0.63)^2 - (0.37)^2 = (0.63 + 0.37)(0.63 - 0.37) = 1.00 X 0.26 = 0.26 Show more…
