Question

2/5 whole power 3into 2/5whole power7 equal to 2/5whole power 2x then find x​

Answer 1

Answer:

(2/5)^3 * (2/5)^7 = (2/5)^2x

When bases are same, powers can be added so

(2/5)^7+3 = (2/5)^2x

(2/5)^10 = (2/5)^2x

Bases on both the sides are equal so powers can be compared

==> 10 = 2x

Hence x = 5
