The Formal Method:
(5)2 + (10)2 = (5)2 + (2 x 5)2 = (5)2 + (2)2(5)2 = 52 ( 1 + 4) = 52 (5) = (25) (5) = 125
The Easy Method:
52 = 25
102 = 100
52 + 102 = 25 + 100 = 125 .
7 + 90 / 9 + 10 + 42 - 7 7 + 10 + 10 + 16 - 7 36
10
(5.9x^3 + 3.4x^2 - 7) - (2.9x^3 - 9.6x^2 + 3) = 3x^3 +13x^2 -10
It is: 3^2 plus 2^3 = 17 meaning 9 plus 8 = 17
16 plus 10 plus 8 plus 6 plus 2 is equal to 42.
1 000 000 + 500 000 + 50 000 + 200 + 60 + 5 OR 10 to the power 6 plus 5 x 10 to the power 5 plus 2 x 10 to the power 4 plus 2 x 10 to the power 2 plus 6 x 10 plus 5
92,054,000 is the answer.
If you mean: 2^6 plus 4^2 = 80 and in standard form it is 8.0*10^1
4
(3x + 2)(x + 5)
10 ( x = -3)
X power 2 (X power 2 - 10) and Y power 2 (1+9)
s = 20
2 and a half plus 2 and a half plus 10 plus 10 = 25
(b - 1)(3b - 10)
The discriminant is 900.
30 + 3-2 = 10/9
