Answer 2

The value given in the question be

$(9.9)^{2}\times 1.79$

Find out the estimate value of (9.9)²× 1.79

To calculate

Let us consider

x = (9.9)²× 1.79

this is written in the simple form  as follows

x = 9.9 × 9.9 × 1.79

x = 98.01 × 1.79

now by doing the simple multiplication of the values given in above equation

we get

x = 175.4379

Thus the estimate value of the (9.9)²× 1.79 is 175.4379.
