Question

if 5 to the power x is equal to 125 to the power minus 1 find the value of 2x and 3X x 4 x​

Answer 1

Answer:

5^x = 125^(-1)

5^x = 1/125

5^x = 1/(5³)

5^x =5^(-2)

On comparing,

x = (-2)

2x = 2*(-2) = (-4)

3x = 3*(-2) = (-6)

4x = 4*(-2) = (-8)

3x x 4x = 3*(-2) * 4*(-2)

            = (-6) * (-8)

            = 48
