Answer 2

Given,

The term for evaluation is = (10.2)²

To find,

To evaluate the given term by using algebraic formula.

Solution,

We can simply solve this mathematical problem by using the following mathematical process.

Given term

= (10.2)²

= (10+0.2)²

= (10 + 2/10)²

(This form can be used to apply (x+y)² = x²+2xy+y² formula.)

Here, x = 10

y = 2/10

So,

(x+y)²

= x²+2xy+y²

= (10)² + (2×10×2/10) + (2/10)²

= 100+4+4/100

= 104 + 0.04

= 104.04

Hence, the final answer is 104.04
