What is the value of 2^{6}?
2^{6} = 2 x 2 x 2 x 2 x 2 x 2 = 64
What is the value of 10^{4}?
10^{4} = 10 x 10 x 10 x 10 = 10000
What is the value of (-2)^{4}?
(-2)^{4} = (-2) x (-2) x (-2) x (-2)
= (-2) x (-2) x (-2) x (-2)
= (+4) x (-2) x (-2)
= (+4) x (-2) x (-2)
= (-8) x (-2)
= 16
What is the value of (-3)^{3}?
(-3)^{3} = (-3) x (-3) x (-3)
= (-3) x (-3) x (-3)
= (+9) x (-3)
= -27
