Question

Find the value of b. B² = 256

Answer 1

`B^2=256`

`\mathrm{For\:}x^2=f\left(a\right)\mathrm{\:the\:solutions\:are\:}x=√(f\left(a\right)),\:\:-√(f\left(a\right))`

`B=√(256),\:B=-√(256)`

`√(256)`

`\mathrm{Factor\:the\:number:\:}\:256=16^2`

`=√(16^2)`

`=16`

`-√(256) =-16`

`B=16,\:B=-16`
