Answer:
-3/4
Step-by-step explanation:
A calculator can work this for you. All you need to do is substitute the numbers for the variables.
yx^y -xy^x
= 4(1/2)^4 -(1/2)(4^(1/2))
= 4/16 - 1/2√4 = 1/4 - 1
= -3/4
b is decreased by 25% which means there will be (-ve) sign.
-3
it like 7-4 but then you change the sign to negative since you chance it earlier.
A=πr(r+h2+r2)
literally just search it up
