The expression (7 \times 7 \times 7) can be written in exponential form as (7^3). This is because the base (7) is multiplied by itself three times.
It is: 18-3D
1,210 = 1.21 × 103
It means that the variable of interest appears as a power in the expression. So, for example, 3x is exponential but x3 is merely cubic. The distinction depends on the position of x.
To express (2 \times 2 \times 2 \times 6 \times 6 \times 6) in exponential form, first count the number of times each base appears. The base 2 appears 3 times, and the base 6 appears 3 times. Therefore, the expression can be written in exponential form as (2^3 \times 6^3).
