how do I solve this ^(1/2) 121-(-5.5)

Question

The problem is v= the squared root of 121-h^2. h has been substituted with -5.5

Answer 1

square root(x) is root(x) or x^1/2 or x^0.5

me thank yu want sq root av [121-h*h],

but first, evaluate with h=-5.5

h*h=30.25

so get root[121-30.25]

=root(90.75)

=95.26279442
