3.9^m-4=10.21

Answer:

(m-4)In(3.9)=In(10.21)

m(In3.9)-4(In3.9)=In(10.21)

m=(In10.21)+4(In3.9)/In3.9

m=7.7672/1.3609

m=5.7074

e^3x>=21

Answer:

Ine^3x>=21

3x=In21

x=In21/3

x=1.0148

Thanks

however

e^3x>=21

Answer:

Ine^3x>=21 You mean ln 21

3x=In21

x=In21/3

x=1.0148 You forgot the "greater than" part
