Question

kindly find the answers for the above questions​​

Answer 1

Answer:

a. (-4)^x = -1024

(-4)^x = √(-4)×(-4)×(-4)×(-4)×(-4)

(-2)^2x= (-2)^10

If the bases are equal we can equate the powers

2x = 10

x = 10/2

x = 5

b. (-3/4)^x = -243/1024

(-3/4)^x = √-3×-3×-3×-3×-3/√4×4×4×4×4

(-3/4)^x = (-3/4)^5

If the bases are equal we can equate the powers

x = 5

Hope my answers are correct. And if correct pls mark it as Brilientest

Answer 2

Answer:

a). (-4)^x = -1024. {1024=4×4×4×4×4=(4)⁵}

=> (-4)^x = (-4)⁵

∴ x = 5

b) (-3/4)^x = -243/1024

{243=3×3×3×3×3=(3)⁵}

{1024=4×4×4×4×4=(4)⁵}

=> (-3/4)^x = (-3/4)⁵

∴ x = 5
