Question

2power X=（128）power1/7×（root2）power4

​

Answer 1

Answer:

x=4

Step-by-step explanation:

2 power x = (128) power 1/7 *√2⁴

2 power x = (128) power 1/7 *√(2²)²

2 power x = (128) power 1/7 *2²

2 power x = (128) power 4/7

2 power x = (2 power 7) power 4/7

cancel 7

2 power x= (2⁴)

=> x=4
