Question

EXPONENT
plz solve this​

Answer 1

Step-by-step explanation:

solve:

1: 2^2x+1= 8

=> 2^2x+1 = 2³

=> 2x+1=3

=> x= 1

2: 5^x =125

=>5^x = 5³

=> x=3

evaluate :

1:. 11^(-7) / 11^(-8)

= (1/11⁷)/(1/11⁸)

= 11⁸/11⁷

= 11⁷*11/11⁷

= 11

2: {3^(-2) *4^(-3)}*2⁵

= 3^(-2) * 4^(-3) * 2⁵

= (1/3)² * (1/4)³ * 2⁵

= 1/9 * 1/64 * 32

= 1/18

hope it helps.
