Find the

mean proportioneel of 28a⁵, b³

b. 7a³

Answer ⤵️

For two numbers a,c the mean proportional b is

b= √ac

So for the first part we have, mean proportional

= √6×24 = √144 =12

For the second part we have, mean proportional

= √360a⁴ ×250a²b² = √90000a⁶b² =300a³b

Answer 2

Step-by-step explanation:

Let the mean proportional be x

So

28

${x}^{2} = 28 {a}^{5 } \times {b}^{3 }$

Taking square root on both sides

$x = + - {a}^{2} b \sqrt{28ab}$
