92=81 402=1,600
1,600+81=1,681
I'm not super sure about this answer so don't leave bad comments!:)
3a squared plus nine = 19a. 3a to the second power = 9a plus 9 = 19a.
No it is not.
16-9+32=16
40 + 9 + 12 = 61
3 to the 2nd power plus 5 x 4 - 9 = 20 32 + 5 x 4 - 9= 9 + 20 - 9= 20
x^2 + 81
30 + 3-2 = 10/9
(x+3)2 = x2+6x+9
Exponents before addition 36 + 59 = 95
7*6 + 22 - 32 = 42 + 4 - 9 = 37
(-7x + 3)(-7x +3)
32 + 52 = 9 + 25 = 34
