Question

the geometric mean of (1+root2)and (7+5root2​

Answer 1

Answer:

Step-by-step explanation:

geometric mean =second term/first term

=7+5rt(2)/1+rt(2)

now rationalise the dnominator the rationalising factor of 1+rt(2) is 1-rt(2)

so (7+5rt(2))*(1-rt(2))/(1-2)

=7-7rt(2)+5rt(2)-10/-1

-3-2rt(2)/-1

=3+2rt(2)[rt means root here]
