Question

If 21+72/3-72=11 +b√2, then express the value of b as a rational number in its standard form.​

Answer 1

Answer:

26.87

Step-by-step explanation:

21+72/3-72=11+b√2

solving equation

21+24-72-11= b√2

38=b√2

squaring both the sides

38×38= b√2 ×b√2

1444 = 2b^2

1444/2=b^2

722= b^2

b=√722

b=26.87
