Question

(4)^-4 x 4^3x=4^5,then x=______​

Answer 1

Answer:

By, a^m×a^n=(a)^mn

We have,

(4)^(-4×3x)= 4^5

since base is same hence powers can be equated

So,

-12x=5

x= -5/12

Answer 2

?

${4}^{ - 4} \times {4}^{3x} =4^5,then \: x=? \\ solution, \\ formula = {1}^{1} \times {1}^{1} = {1}^{1 + 1} . \\ {4}^{ - 4} \times {4}^{3x} =4^5 \\ {4}^{ - 4 + 3x} = {4}^{5} \\ - 4 + 3x = 5 \\ 3x = 5 + 4 \\ 3x = 9 \\ x = \frac{9}{3} \\ x = 3 \: \: answer...$
