Question

3. Find 'x' if

(a) 3x-²÷3-³=3⁴​

Answer 1

Step-by-step explanation:

$\frac{ {3x}^{2} }{ {3}^{3} } = {3}^{4}$

${3x}^{2} = {3}^{4} \times {3}^{3}$

${3x}^{2} = 81 \times 27$

${3x }^{2} = 2187$

${x}^{2} = \frac{2187}{3}$

$x = \frac{ \sqrt{2187} }{ \sqrt{3} }$

$x = 729$

$x = 27$

Answer 2

Answer:

x=3

Step-by-step explanation:

3^x-2/3^-3= 3⁴

3^x-2÷1/3³=3⁴

3^x-2÷1/27=3⁴

3^x-2×27=3⁴

3^x-2=81/27

3^x-2=3

Taking only powers:-

x-2=1

x=1+2

x=3
