Answer:

The value of variable for the expression is x is 9 and y is 16 .

Step-by-step explanation:

Given expression as :

( 2 × [tex]10^{16}[/tex] ) + ( 7 × [tex]10^{16}[/tex] ) = x × [tex]10^{y}[/tex]

Or, ( 2 +7 ) × [tex]10^{16}[/tex] =  x × [tex]10^{y}[/tex]

or,  9 × [tex]10^{16}[/tex] =  x × [tex]10^{y}[/tex]

Now, comparing left hand side and right hand side of equation

∵ left hand side =   9 × [tex]10^{16}[/tex]

And right hand side = x × [tex]10^{y}[/tex]

So, from comparing

The value of x and y is

x = 9    and

y = 16

Hence The value of variable for the expression is x is 9 and y is 16 . Answer
