Question

1. Express in exponential form.
256 x 81
64 x 729
DIf 22x – 3 = (64)”, find the value of x.​

Answer 1

Answer:We have to express the following in exponential form,256/64×81/729Now if we look at the first fraction that is 256/64 we will see that 64 x 4 = 256and the second fraction is 81/729 = 81 x 9 = 729So after simplifying the above we get,= 4/9= (2)²/(3)²hence 256/64×81/729 = (2)²/(3)²
