its urgent !! ✌✌☹️​

Answer 1

Step-by-step explanation:

1) 3^x = 243

243 = 3⁵

since bases are same

so x = 5

2) (-2)^x × (-2)²x = (-2)-⁹

since bases are same

so x+2x= -9

x = -3

3) 5^x + 5^x+1 = 125

125 = 5²

since bases are same

x+x+1 = 2

x= 1/2

4) 7^5x/7^7x = 1/2401

2401 = 7⁴

1/7⁴ = 7-⁴

so since bases are same

5x-7x = -4

-2x = -4

x= 2

hope it helps you the rest can be solved by the same method
