Answer 1

Answer:

a) (-5)^2x-3 = -125

(-5)^2x-3 = (-5)^3

2x-3 = 3

2x = 3+3

x = 6/2

x = 3

b) 7^4x-5 = 343

7^4x-5 = 7^3

4x-5 = 3

4x = 3+5

x = 8/4

x = 2

c) (9)^x+1 = 729

9^x+1 = 9^3

x+1 = 3

x = 3-1

x = 2

d) 11^6 x 11^4-x = 11^8

11^6+4-x = 11^8

11^10-x = 11^8

10-x = 8

-x = 8-10

x = 2
