What is the value of st: (6r) if r=5, s=32, and t=45

S = 32 and t = 45

You replace the letters into numbers ...

Since (st) is the same thing as (s * t), it would be 32 * 45, which equals to 1,440.

Then replace the r with 5, so now it's (6 * 5), instead of (6r).

st : (6r) → 1,440 : 30 = 48

Value of st : (6r) = 48
