Question

If a, b, c are in proportion & if a = 3, c = 23 find b. explain please​

Answer 1

Step-by-step explanation:

it is given that 3,b,27 are in continued p

$\frac{3}{b} = \frac{b}{27 } \\ = {b}^{2} = 3 \times 27 \\ = {b}^{2} = 8 \\ =b = \sqrt{81} = 9 \\ ∴Thus \: the \: value \: of \: b \: is \: 9$

Answer 2

Answer: a/b=b/c,3/b=b/23,b^2=23×3=69,b=8.3
