Question

find the value of x
1-(-2)¹¹÷(-2)⁹=(-2)^2x

2-(47)^x÷47^21=(47)^21

3-(2/3)^26÷(2/3)^22 =(2/3)³​

Answer 1

Answer:

1) (-2)^11÷(-2)^9=(-2)^2x

= (-2)^11-9=(-2)^2x

= (-2)^2=(-2)^2x

= 2 =2x

= 2x = 2

= x = 2/2

= x = 1 (Answer)

2) (47)^x ÷ 47^21=(47)^21

= (47)^x-21=(47)^21

= x- 21= 21

= x = 21+21

= x = 42 (Answer)

About question no.3 I think that the question is not mentioned well...
