Find the quotient 21 π to the power of six π divided by seven ππ.
In order to answer this question, we need to consider one of the laws of indices: π₯ to the power of π divided by π₯ to the power of π is equal to π₯ to the power of π minus π. When we are dividing, we need to subtract the exponents or indices.
Letβs consider 21 π to the power of six π or π to the power of one divided by seven ππ. Well, 21 divided by seven is equal to three. π to the power of six divided by π is π to the power of five as six minus one is five. And π divided by π is π to the power of zero as one minus one is zero.
As we know that anything to the power of zero is equal to one, the answer is three π to the power of five. 21 π to the power of six π divided by seven ππ is three π to the power of five.
