for such questions we continuously evaluate the powers of both side of the equations. Q1. 5^(9-3x) = 100 twenty 5 100 twenty 5 is same as writing 5^2 thismeans that 9-3x = 2, shall we detect x 9 - 3x = 2 -3x = -7 x = 7/3 Q2. 4^(7 - 3x) = (a million/16) same theory applies. a million/16 = a million/(4^2) = 4^-2 so 7 - 3x = -2; sparkling up for x 7 - 3x = -2 -3x = -9 x = 3 Q3. 36 = b^(2/3) this question looks frustrating yet is uncomplicated. we sud use opposite operation to discover b. b has been raised to 2/3....wat sud we do to acquire obly "b"..raised to skill a million. we enhance [b^(2/3)] to the skill 3/2. we ought to coach this operation on each and each side of the equation: 36^(3/2) = [b^(2/3)]^(3/2) 216 = b i desire my rationalization became sparkling adequate for Q3. :)

3x-5=9
transpose -5 with 9 so it became +5
3x=9+5
to get rid of 3 devide it with 3
3x/3= 14/3
cancel the two 3 in 3x/3 coz 3/3=1
x=14/3
final answer
