Determine whether the following sets form subspaces of R3 . (a) {(x1,x2,x3)T|x1+x3=1}
(b) {(x1,x2,x3)T|x1=x2=x3}

Step-by-step explanation:

. fvv. ,.

è465⁸

step-by-step explanation:

given expression is .

now we need to simplify the given expression .

we know that square root is equivalent to the power 1/2. so that means we can take half of the exponents to get the square root of given expression.

expanding that will give a very very large number so let's keep answer in exponent form.
