2. What is the value of i? 

• √-1

• √-2

• √1

• √-2

Answer explanation

Imaginary numbers are numbers that result in a negative number when squared. They are also defined as the square root of negative numbers.

An imaginary number is the product of a non-zero real number and the imaginary unit "i" (which is also known as "iota"), where i = √(-1) (or) i² = -1.

The degree of a linear equation is:

• 0

• 1

• 2

• 4

Answer explanation

A linear equation can be defined as an equation with mainly one or two variables, and each of these variables is raised to power 1, which states that every variable is raised to a power, not more than one. Hence the Degree of a Linear Equation is always one due to the variables being continually raised to the degree one

2. A coin is tossed 7 times. Find the probability of getting at least one head. 

• 1. 127/128

• 1/128

• 255/256

• 1/256

Answer explanation

Solution: 2^7=128

Odds of getting no heads=1/128

1-1/128=127/128

7. The (a)   , is a triangle figure that has ten points sorted in four rows: one, two, three, and four points in each row. 

Answer explanation

The tetractys (Greek: τετρακτύς), or tetrad,^[1] or the tetractys of the decad^[2] is a triangular figure consisting of ten points arranged in four rows: one, two, three, and four points in each row, which is the geometrical representation of the fourth triangular number.

How many zeros are there in a googol?

• 10

• 100

• 1000

• 10000

Answer explanation

A googol is 10 to the 100th power, which is 1 followed by 100 zeros. While this is an unimaginably large number, there's still an infinite quantity of larger numbers. One such number is googolplex, which is 10 to the power of a googol, or 1 followed by a googol of zeros.

9. How many different combinations does a 3 by 3 rubik’s cube have?

• 43 252 003 274 489 956 000

• 43 252 003 474 489 856 000

• 43 252 003 274 589 856 000

• 43 252 003 274 489 856 000

Answer explanation

(1/2) (8! x 3⁷) (12! x 2¹¹) = 43,252,003,274,489,856,000
