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
