Final answer:
When writing expressions in the form M^(1) and M^(2), the term for M^(1) is the same as the base, and the term for M^(2) is the square of the base.
Step-by-step explanation:
When writing an expression in the form M^(1) and M^(2), we are using exponents or powers to represent repeated multiplications. The exponent 1 represents raising the base to the power of 1, which is the same as not using an exponent at all. Therefore, the term for M^(1) would be the same as the base, such as 5x or -4x. The exponent 2 represents raising the base to the power of 2, which is equivalent to squaring the base. So, the term for M^(2) would be the square of the base, such as (5x)^2 or (-4x)^2.
