Answer 2

To simplify the expression :

25⁴ ÷ 5³

Solution :

$\implies \tt{ \ { {(5}^{2})}^{4} \div {5}^{3} }\\ \implies \tt{ {5}^{8} \div {5}^{3} } \\ \implies \tt{ {5}^{8 - 3} } \\ \implies \tt{ {5}^{5} }$

Laws of exponents used here :

${(x}^{m} )^{n} = {x}^{mn}$

${x}^{m} \div {x}^{n} = x^{m - n}$

Something that helps :

• Exponents are also called Powers or Indices.
• To write the large numbers in short form, we use exponents.
• The exponent of a number tells how many times to use the number in a multiplication.
• Any number with zero exponents is equal to one irrespective of the base.
• If we have to multiply the powers which have the same base then we have to add the exponents.
