Question

If 3^3x-1/9 = 27, find the value of x

Answer 1

Answer:

Heya dear

here your goes like this dear !!

3^(2x+1) / 9 = 27

by transposing 9 from LHS to RHS then it will be ( ×9 )

3^(2x+1) = 27×9

3^(2x+1) = 243

3^(2x+1) = 3^5

bases are equal , so equate powers

2x+1 = 5

by transposing 1 frm LHS to RHS then it will be (-1)

so now , 2x = 5-1

2x = 4

x = 4/2

x = 2

I hope it helps you dear......

Thank my answer and mark as brainliest if it is helpful to you dear...
