Write using an exponent: 1×7×7×7×7×7a. 1×7×5b.1 * {7}^(5)c. 1 * {5}^(7)

Question

Write using an exponent: 1×7×7×7×7×7a. 1×7×5b.
`1 * {7}^(5)`c.
`1 * {5}^(7)`

Answer 1

In the expression, the number 7 is multiplied to itself 5 times or five 7's are multiplied with each other. So exponential expression for the equation is,

`1\cdot7\cdot7\cdot7\cdot7\cdot7=1\cdot7^5`

Option B is correct.
