To simplify the expression \( 10m^2 \cdot 3m^5 \), follow these steps:
-
Multiply the coefficients:
- The coefficients are 10 and 3.
- \( 10 \cdot 3 = 30 \).
-
Combine the variables:
- You can combine the powers of \( m \) by adding the exponents.
- \( m^2 \cdot m^5 = m^{2+5} = m^7 \).
Putting it all together, we have:
\[ 10m^2 \cdot 3m^5 = 30m^7 \]
So the simplified expression is \( \boxed{30m^7} \).
