HYao Section f(z) za +4, g(z) V8 -z. 5. (10 points) Find gu(z)) and write down the domain when 6. (o points) Among all pairs of numbers r, v such that z+3y 4, what is it the maximum or minimum value of 2r2 ry. 7. (10 points) Solve for x: a). In z 5. b). log r 3.

Solution

7)by properties of logaritham log_ba=c =>a=b^c

a)

ln x=5

log_ex=5

x=e⁵

b)log x=3 , when base is not given , we have to take it as 10

log₁₀x=3

x=10³

x=1000
