Question

0.4^2+0.3^2-0.1^2

Answer 1

Is is just simplifying?

Answer 2

0.4^(2)+0.3^(2)-0.1^(2)

Squaring a number is the same as multiplying the number by itself (0.4*0.4).
0.4*0.4+0.3^(2)-0.1^(2)

Multiply 0.4 by 0.4 to get 0.16.
0.16+0.3^(2)-0.1^(2)

Squaring a number is the same as multiplying the number by itself (0.3*0.3).
0.16+0.3*0.3-0.1^(2)

Multiply 0.3 by 0.3 to get 0.09.
0.16+0.09-0.1^(2)

Squaring a number is the same as multiplying the number by itself (0.1*0.1).
0.16+0.09-0.1*0.1

Multiply 0.1 by 0.1 to get 0.01.
0.16+0.09-0.01

Add 0.09 to 0.16 to get 0.25.
0.25-0.01

Subtract 0.01 from 0.25 to get 0.24.
0.24
