Question

Find x, if 2-3÷ 2

7 = 4​

Answer 1

3 + x = 7. will be false if any number except 4 is substituted for the variable. The value ... 4(3) - 2 = 3(3) + 1. 12 - 2 .

Answer 2

Answer:

Given equation is (3−2)−13×(−23)8=(3−2)−2x+1

To find out: The value of x.

We know that, (ba)m=(ab)−m

Hence, (−23)8=(3−2)−8

So, the given equation becomes,

(3−2)−13×(3−2)−8=(3−2)−2x+1

We also know that, am×an=am+n

Hence, the equation becomes,

(3−2)−13−8=(3−2)−2x+1

(3−2)−21=(3−2)−2x+1

Since, the base on both sides is equal, the exponents must also be equal.

So, −21=−2x+1

⇒2x=1+21

⇒2x=22

⇒x=222

∴ x=11

Hence, the solution of the given equation is x=11.
