<em>So to solve for a variable, you have to isolate that variable onto one side.</em>
<h3>14.</h3>Firstly, multiply both sides by j:
Next, divide both sides by k and <u>your answer will be: </u>
Firstly, add g on both sides:
Next, multiply both sides by 5 and <u>your answer will be: </u>
Firstly, subtract 5p on both sides:
Next, divide both sides by 9 and <u>your answer will be </u>
A x = 0
using the law of exponents = 1
for (6² )^ x = 1 then x = 0
B note that = 1 ⇒ x = 1
2 → 2^8 × 3^(-5) × 1^(-2) × 3^(-8) × 2^(-12) × 2^(28)
= 2^(8 -12 + 28) × 1 × 3^(- 5 - 8)
= 2^24 × 3^(- 13) = 2^(24)/3^(13) = 10.523 ( 3 dec. places)
