Consider 7 x 10 to the third power. write a pattern to find the value of expression

Write an expression with the given equation
=> 7 x 10 to the third power.
this equation uses an exponent.
=> 7 x 10^3, in this equation, 10 will be multiplied 3 times as what the exponent asks
=> 7 x ( 10 x 10 x 10)
=> 7 x 1 000
=> 7 000
Therefore, 7 x 10 to the third power is equals to 7 000. This can also explains as there are 7 1 000s in 7 000.
