Question

Simplify m^9 m^−3.
A. -m^12
B. 1 / m^27
C. 1 / m^6

D. m^6

Answer 1

I will use the law of exponent below

⇒if you re multiplying powers of them same base, keep one base and add the exponents mathematically we say:

`x^(n) *x^(n) \\=x^(n+n)`

`=m^(9+(-3)) \\=m^(9-3) \\=m^(6)`

OPTION D is the solution
