Can you answer these math questions please

4) Solve, giving the answers exactly or correct to 3 significant figures.
B) 4^X< lOa=
Exercise 18D In this exercise, use logs only when necessary.

1) Solve for X
E) 3^4X = 2
G) 3^x- 2 = 28
H) 5^3X =7
I) 7^-X=1
J) Log 2 X= 4
K) Log x 4 = 2
L) Log4 2 = X

Thanks i'm really stuck :)

4^X< lOa hey is that antilog i donot understand


E)4x*log3=log2
so,x=log3/(4log2)
G)3^X=30
so,Xlog3=log30
so,X=log3/log30

H)3Xlog5=log7
x=log7/(3log5)

I)-Xlog7=log1=0
so X=0

J)log 2 base 4 =4 right?
from definition of log X=2^4=16 chck it

K)from definition 4= X^2 so X=2

L)Log4 2 = log 4 4^(1/2) =x
so,1/2 =x
so x=1/2
ih u have furthur enquiry pls mail me

400 : 3 x yyztp+20= 0
