asdfasdfd The expression is: (0.8) 2 +(0.4) 2 (0.8) 4 -(0.4) 4 ? ?? Shortcut (No long calculation) Recognize the identity: a 4 -b 4 =(a 2 -b 2 )(a 2 +b 2 ) So, a 2 +b 2 a 4 -b 4 ? =a 2 -b 2 Here, a=0.8 b=0.4 Therefore, =0.8 2 -0.4 2 Now, 0.8 2 =0.64,0.4 2 =0.16 0.64-0.16=0.48 ? Answer: 0.48 aefadsf 06-30-2026 10:24 AM

Solution Actually it simplly used the formula (a^2 -b^2) =(a+b)(a-b) Abhi 06-30-2025 10:33 AM

Explanation Question: (0.8)^4 – (0.4)^4 / (0.8)^2 + (0.4)^2 Answer: (0.8*0.8*0.8*0.8)-(0.4*0.4*0.4*0.4) / (0.8*0.8) + (0.4*0.4) You can now cancel 0.8*0.8 in the numerator with the 0.8*0.8 in the denominator, in the same way, do for 0.4 , Therefore we get, =(0.8*0.8)-(0.4*0.4) =0.64-0.16 =0.48 Priscilla 05-25-2024 04:21 AM
