if v belongs to V, then we can find scalars a1,a2,...,an, such that v=a1*v1+a2*v2+...+an*vn, L1(v)=L1(a1*v1+a2*v2+...+an*vn) =a1*L1(v1)+a2*L1(v2)+...+an*L1(vn) =a1*L2(v1)+a2*L2(v2)+...+an*L2(vn) =L2(a1*v1+a2*v2+...+an*vn) =L2(v)

Find the geometric mean of 5 and 7

dsp73

Answer:

$\sqrt{35}$

Step-by-step explanation:

A geometric mean is just $\sqrt[n]{term one * term two * term three * etc.}$ , where n is the number of terms.

i.e. Geometric mean of 5, 6, 7: there are three values, so the mean is $\sqrt[3]{5*6*7}$

3^-1 ___ 1/4 a > b < c =

Readme [11.4K]

Answer:

a ">"

Step-by-step explanation:

3 to the power negative one (-1) is the same as 1/3 (one unit divided by 3).

1/4 on the other hand is one unit divided by 4.

Dividing one object into three parts (think for example a chocolate bar) gives you a larger (greater) piece than dividing it into four equal pieces.

Therefore 1/3 > 1/4
