Find the numerical equivalent of 7^2.7^3

1 answer

To find the numerical equivalent of \( 7^2 \cdot 7^3 \), you can use the property of exponents that states:

\[ a^m \cdot a^n = a^{m+n} \]

In this case, \( a = 7 \), \( m = 2 \), and \( n = 3 \). Applying the property:

\[ 7^2 \cdot 7^3 = 7^{2+3} = 7^5 \]

Now, calculate \( 7^5 \):

\[ 7^5 = 7 \cdot 7 \cdot 7 \cdot 7 \cdot 7 \]

Calculating it step by step:

\[ 7^2 = 49 \] \[ 7^3 = 7 \cdot 49 = 343 \] \[ 7^4 = 7 \cdot 343 = 2401 \] \[ 7^5 = 7 \cdot 2401 = 16807 \]

Thus, the numerical equivalent of \( 7^2 \cdot 7^3 \) is:

\[ \boxed{16807} \]
