Answer 1

ˣa. 4ˣ = 1/16 = 4⁻²
x = -2

b. x⁻³ = 1/27 = (3)⁻³ --> x = 3

c. 2ˣ = 1/16 = 2⁻⁴ --> x = - 4

d. x⁻³ = (- 1/8)= (-1/2)³= (2)⁻³ --> x= 2

e. 5ˣ = 1/625 = (5⁻⁴)
x = - 4

f. x⁻⁴  = 1/81= 3⁻⁴ --> x = 3

g. 2ˣ = 128 --> 2ˣ = 2⁷ --> x = 7

h. 343 = x³ --> 7³ = x³ --> x = 7

i. 6ˣ = 216 = 6³ --> x = 3

j. 15ˣ = 1/225 = 15⁻²
x = - 2
