Solution
We have to find the value of `(256)^0.16 xx (256)^0.09`So,
By using law of rational exponents
`a^m xx a^n = a^(m+n)` we get
`(256)^0.16 xx (256)^0.09 = (256)^0.16 xx (256)^0.09`
=`(256)^(0.16+0.09)`
= `256^(0.25)`
=`(256)^(25/100)`
`(256)^0.16 xx (256)^0.09 = 2^(8 xx 25/100)`
= `2^(8 xx 25/100)`
` = 2^(8 xx 1/4)`
` = 2^(8 xx 1/4)`
= 4
The value of `(256)^0.16 xx (256)^0.09 `is 4
