Answer 1

Explanation:

11)
`4b^{(-3)/(4)}+10=(21)/(2)\\\\4b^{(-3)/(4)}=(21)/(2)-10\\\\4b^{(-3)/(4)}=(21)/(2)-(10*2)/(1*2)\\\\4b^{(-3)/(4)}=(21)/(2)-(20)/(2)\\\\4b^{(-3)/(4)}=(21-20)/(2)\\\\4b^{(-3)/(4)}=(1)/(2)\\\\b^{(-3)/(4)}=(1)/(2*4)\\\\\frac{1}{b^{(3)/(4)}}=(1)/(8)\\\\1*8=b^{(3)/(4)}\\\\2^(3)=( b^{(1)/(4)})^(3)\\\\2= b^{(1)/(4)}\\\\Take power 4 both sides,\\2^(4)=b\\b=16`
