The first is R =24. Does this mean that I should convert 0.75 to 3/4 then multiplY0 24 by 3 and find the answer raised to the power 4?
2 2 3
(2) R +R =R . How is this possible?
0.5
(3) R - 90=0 Does this mean that I convert 0.5 to 1/2 and then find a number whose square root is 90 and do my calculations from there?

first, please clarify. you can just type "^" to mean power. for example, x^2 means $x^2$ . no need to go through fancy formatting exercises. the forum takes out the spaces anyway, so you just waste your effort

do you mean

$R^{0.75} = 24$

$R^2 + R^2 = R^3$

and

$R^{0.5} - 90 = 0$ ?
