i = sqrt(-1) i^2 = sqrt(-1)*sqrt(-1) = -1 i^3 = I^2 * I = -sqrt(-1) i^4 = I^2 * I^2 = -1 * -1 = 1 i^100 can be broken down. The easiest way is to...
If 2^x + 2^x + 2^x + 2^x = 2^16, what is the value of x? Add up the left side, we get: 4(2^x) = 2^16 But 4 = 2^2, so we have: 2^2(2^x) = 2^16...
A road is resurfaced at the rate of 2 1/5 km per day. if it takes 9 days to complete the job, how long is the road? 2 & 1/5 = 11/5 9 / 11/5 is...
Write in decimal form: 3 cm 7 mm = ? cm Remember that 1 cm = 10 mm Which means 1 mm = 1/10 cm = 0.1 cm So 7 mm = 7/10 cm = 0.7 cm Therefore, 3...
Volume of a cube is s^3 where s is the length of one side. V = 64 s^3 = 64 Take the cube root of each side: s = 4 since 4^3 = 64 Surface Area of...
If the perimeter of square C is triple the perimeter of square D, the area of square C is how many times the area of square D? A. 1/3 B. 1 C. 3...
