13*8=104
104*2=
<em>208</em>
Step-by-step explanation:
Answer:
The given expression
on multiplying is 
Step-by-step explanation:
Consider the given two expressions
and 
We have multiply both expressions,

To multiply two terms first multiply constant numbers that is 6 × 2 = 12
For x , y and z apply property of exponent,

Then power of x together will be,

Similarly for y powers,

Since first term do not have any expression for z so it will remain same.
Thus, the given expression on multiplying become,
is 
The y represents "some number," so in this case some number divided by three is the right answer
5^2 + x^2=8^2
25+x^2=64
X=6.2
