Question

Find value of:
(2)^1.56 * (3)^1.78 * (7)^0.78 * (84)^0.22 = ?

Answer 1

Answer:252

Step-by-step explanation:

(2)^1.56 * (3)^1.78 * (7)^0.78 * (84)^0.22

=> (2)^1.56 * (3)^1.78 * (7)^0.78 * (4*3*7)^0.22

=> [(2)^1.56 * 4^0.22] * [(3)^1.78 * (3)^0.22] * [(7)^0.78 * (7)^0.22)]

=> [(2)^1.56 * 2^0.22 * 2^0.22] * [(3)^1.78 * (3)^0.22] * [(7)^0.78 * (7)^0.22)]

=> [2^(1.56+0.22+0.22)] * [3^(1.78+0.22)] * [7^(0.78+0.22)]

=> [2^2] * [3^2] *[7^1]

=> 4*9*7

=> 252
