Question

Find the value of x if (-3/4)-⁶ X (-3/4)-⁴ = (-3/7) ²×​

Answer 1

Answer:

- 5

Explanation:

${( \frac{ - 3}{4} )}^{ - 6} \times {( \frac{ - 3}{4} )}^{ - 4} = {( \frac{ - 3}{7} )}^{2x}$

Powers are added when bases are same then,

$- 6 + ( - 4) = 2x$

$2x = - 10$

$x = \frac{ - 10}{2}$

$x = - 5$
