TION 4 Write the following in exponential form \( x \times x \times x \times x \) \( x \times x \times x \times x=x^{4} \) \( 10 \times 10 \times 5 \times 5 \times 5 \)

To write \( 10 \times 10 \times 5 \times 5 \times 5 \) in exponential form, we can group the numbers by their bases: \( 10^2 \) for the two tens and \( 5^3 \) for the three fives. Therefore, the expression can be written as: \[ 10^2 \times 5^3 \]
