Question

Make b the subject of formular​

Answer 1

`\sf b=(a)/(50x^2)`

Explanation:

`\sf x =(1)/(5) \sqrt{(a)/(2b) }`

Multiply both sides by 5.

`\sf x*5 =(1)/(5) \sqrt{(a)/(2b) } *5\\\\\sf 5x =\sqrt{(a)/(2b) }`

Square both sides.

`\sf (5x)^2 =(a)/(2b) \\\\25x^2=(a)/(2b)`

Multiply both sides by 2b.

`\sf 25x^2=(a)/(2b)\\\\25x^2*2b=a\\\\50x^2b=a`

Divide both sides by 50x².

`\sf b=(a)/(50x^2)`
