Firstly, let's take first factor:
(y^3)^2 = y^(3*2) = y^6
and then:
y^6 * y^7 = y^(6 + 7) = y^13
the third and forth option:
9.2 × 10-9
3.4 × 10-10
So the length of the house is 15 so 15 x 2 or 15+15= 30. And the withht is 4 so 4 x 2 or 4+4= 8 so 30+8= 38
Size 40 is the cheapest, because the formula to find lowest price of unit is dividing the price by the unit. so 5.49/24≈ 0.23, 8.00/40=0.2, 15.99/64≈ 0.25
