Question

(2×+10^16)+(7×10^16)= x×10^y​

Answer 1

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

Explanation:

Given expression as :

( 2 ×
`10^(16)` ) + ( 7 ×
`10^(16)` ) = x ×
`10^(y)`

Or, ( 2 +7 ) ×
`10^(16)` = x ×
`10^(y)`

or, 9 ×
`10^(16)` = x ×
`10^(y)`

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

∵ left hand side = 9 ×
`10^(16)`

And right hand side = x ×
`10^(y)`

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
