Question

Please answer dis ques​

Answer 1

Step-by-step explanation:

1.(2x+1/2x)²=3²

4x²+2(2x)(1/2x)+1/4x²=9

4x²+2+1/4x²=9

4x²+1/4x²=9-2

4x²+1/4x²=7

2.(4x²+1/4x²)²=7²

16x²+2(4x²)(1/4x²)+1/16x2=49

16x²+2+1/16x²=49

16x²+1/16x²=49-2

16x²+1/16x²=47

Answer 2

Answer:

Step-by-step explanation:

1>  2x+1/2x = 3

squaring on both

(2x+1/2x) = 9

4x²+1/4x²+2 = 9

4x²+1/4x² = 7

2> (4x²+1/4x²)² = 49

16x to the power 4+2(4x²)(1/4x²)+1/16x to the power 4 =49  

16x to the power 4 +2+1/16x to the power 4 =49

16x to the power 4 +1/16x to the power 4=49-2

16x to the power 4 +1/16x to the power 4=47
