Question

help please with working.

Answer 1

q1: 4
4^3 = 64
8^2 = 64

q2: -3
14-17 = -3

Answer 2

Q1 - The equation to solve the problem would be:

$x^{3} = (x * 2)^{2}$

$x^{3} = 2x^{2}$

$x^{3} = 4x^{2}$

$x^{3} - 4x^{2} = 0$ → we apply the exponent rule

$x^{2} (x - 4) = 0$ → we use the zero factor principle

$x - 4 = 0$

$x = 0 + 4$

$x = 4$

The answer is 4, and you can prove it:

The cube of 4 is 64. The double of 8, and 8 squared is also 64.

Q2 - The way of solving the problem would be:

14 - 17 = anwer, becuase the temperature dropped which means the temperature went down.

14 - 17 = -3 degrees

Hope it helped,
