V = side³

V = (y⁵)³

V = y¹⁵

2¹⁺⁴ +  0 ! =

2⁵ +  0 !  =

2⁵ + 1 =

32 + 1  =

33

Good answer, rosala.....!!!

6(8)=36(-7+5x)

48 = -252 + 180x    add 252 to both sides

300 = 180x              divide both sides by 180

300/180 = x  = 30/18 = 5/3

12) 49=7^2

log₇ 49 = 2

15)1/10=10^-1

log (1/10) = -1

10) log(little2)9-log(little2)3

log₂ 3² - log₂ 3  =

2log₂ 3 - log₂ 3 =

log₂ 3

16)log₇x+log₇y-log₇z   =

log₇ [(x y) / z)]

Thanks, rosla !!

y = log (2x)

22)  log₈ 8  .......this just asks, what power do we put on 8 to raise it to itself?? Answer.....1

26) log₅-25.......we can't take the log of a negative number (or 0).....this is undefined.......

We have

12/20 =

6/10 =

60%
