Question

1) Using the laws of exponents, find the value of x. 128 x 2* = 2-4 ​

Answer 1

Answer:

$128 \times 2x = 2 4 \\ 2x = \frac{24}{128} \\ \frac{12}{64} = \frac{6}{32} = \frac{3}{16} \\ 2x = \frac{3}{16} \\ x = \frac{3}{16} \div 2 \\ x = \frac{3}{16} \times \frac{1}{2} \\ x = \frac{3}{32} \:$

This is your solution
