Question

(2×+10^16)+(7×10^16)= x×10^y​

Answer 1

Answer:

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

Step-by-step 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
