Question

Work out $(1)^{5} , (-1)^{3} , (-1)^{4} , (-10)^{3} , (-5)^{4}$.​

Answer 1

Answer:

( i ) We have $(1)^{5}$ = 1 × 1 × 1 × 1 × 1 = 1

In fact, you will realise that 1 raised to any power is 1.

( ii ) $(-1)^{3}$ = (-1) × (-1) × (-1) = 1 × (-1) = -1

( iii ) $(-1)^{4}$ = (-1) × (-1) × (-1) × (-1) = 1 × 1 = 1

You may check that (-1) raised to any odd power is (-1), and (-1) raised to even power is (+1).

( iv ) $(-10)^{3}$ = (-10) × (-10) × (-10) = 100 × (-10) = -1000

( v ) $(-5)^{4}$ = (-5) × (-5) × (-5) × (-5) = 25 × 25 = 625
