2a to the power of m: A is the base, M is the exponent, the result is the power, and 2 is the coefficient.
Formula: M power of A * N power of A =(M+N)A power, the same base is multiplied, the base is unchanged, and the exponents are added.
(M power of A) = m*n power of A, with the same power, multiplied exponentially.
The m power of a/the n power of a = the (m-n) power of a, same base powers is multiplied, the base number is unchanged, and the exponent is subtracted.
Algebraic multiplication: take each monomial apart and multiply it by the coefficient, according to the above formula.
For example: 2a (cubic of B) * 7 (quadratic of A) B.
= 2 * A * (cubic of B) * 7 * (quadratic of A) * B.
= (2 * 7) * (quadratic of a * a) cubic of b * b)
=14 * the third power of a * the fourth power of b
Finally, remove the multiplication sign.
