Write using exponents. Work from left to right on the grid.

7 • 7 • 7 • 7

Answer 1

I assume the question is asking for 7 * 7 * 7 * 7 as an exponent? If so, then it should be written as 7^4.

Answer 2

7 * 7 = 49 * 7 = 343 * 7 = 2401

Move the decimal so there is one non-zero digit to the left of the decimal point. The number of decimal places you move will be the exponent on the 10. If the decimal is being moved to the right, the exponent will be negative. If the decimal is being moved to the left, the exponent will be positive.

2.401 × 10^3
