Answer 1

Step-by-step explanation:

a) 2x=4

x=2

b) x-1=3

x=3+1

x=4

Answer 2

Answer:

a) 2

b) 3

Step-by-step explanation:

a) (-15/8)^2x=(-15/8)^4

we know that bases are equal then exponents should be equal

then 2x=4

x=2.

b) (3/4)^x-1=(3/4)^2

we know that bases are equal then exponents should be equal

then x-1=2

x=3
