Answer:
1/7^7
Step-by-step explanation:
Exponents are simply repeated multiplication.
Here, 1/7 is multiplied by itself 7 times.
Therefore, the exponent is 1/7^7.

System of Linear Equations entered :
[1] 4x - 2y = 2
[2] 3x - 2y = -19
Graphic Representation of the Equations :
-2y + 4x = 2 -2y + 3x = -19
Solve by Substitution :
// Solve equation [2] for the variable x
[2] 3x = 2y - 19
[2] x = 2y/3 - 19/3
// Plug this in for variable x in equation [1]
[1] 4•(2y/3-19/3) - 2y = 2
[1] 2y/3 = 82/3
[1] 2y = 82
// Solve equation [1] for the variable y
[1] 2y = 82
[1] y = 41
// By now we know this much :
x = 2y/3-19/3
y = 41
// Use the y value to solve for x
x = (2/3)(41)-19/3 = 21
Solution :
{x,y} = {21,41}

Answer:
653
Step-by-step explanation:
The surface area of the larger cube is
2(10 x 7) + 2(12x7) + 2(10x12) = 140 + 168 + 240 = 548
The surface area of the smaller cube (minus the surface that is covered by the other figure)
4(8x3) + 1(3x3) = 96 + 9 = 105
105 + 548 = 653
